1. Celestron EclipSmart Solar Filter 75mm – ISO Certified Universal Filter
Celestron EclipSmart Universal Solar Filter for Telescopes
ISO 12312-2 Certified
75mm to 100mm Objective Compatibility
Folds Flat for Storage
USA-Made Solar Film
Pros
- ISO 12312-2:2015(E) compliant for certified safe viewing
- Works with telescopes spotting scopes and DSLR cameras
- Adjustable side panels for secure fit on various optics
- Solar film manufactured in the USA by American Paper Optics
Cons
- Delicate film material requires careful handling
- May need adjustment to fit some odd-size objectives
I picked up this Celestron EclipSmart filter for a small refractor I already owned, and it turned my existing telescope into a capable solar scope for under $25. The folding solar filter design uses an adjustable enclosure with elastic bands that clamp onto objective lenses between 75mm and 100mm in outside diameter. That wide compatibility range means it works with everything from spotting scopes to DSLR camera lenses.
The solar film itself is manufactured by American Paper Optics, the same company that produces eclipse glasses used by observatories and schools. It carries the ISO 12312-2:2015(E) safety certification, which is the international standard for direct solar viewing. The film produces an orange-tinted image of the sun that feels natural and shows good contrast for sunspot observation.
During testing for the annular eclipse rehearsal, I appreciated how compact this filter is. It folds flat, so I could slip it into a camera bag alongside my telescope without adding bulk. The elastic band system held securely during a breezy afternoon session, though I always recommend double-checking the fit before every solar session. Safety should never be rushed.
With 451 customer reviews and a 4.3-star average rating, this is one of the most popular solar filters on Amazon. The majority of users report crisp sunspot views and successful eclipse photography. A few reviewers mentioned the film feels thin and delicate, which is true of all solar film products. Store it in its original packaging between uses and it will last for years.
What Telescopes and Devices It Fits
This filter works with any optical instrument whose objective lens measures between 75mm and 100mm in outside diameter. That covers many popular small refractors, spotting scopes, and camera lenses. If you own aCelestron Travel Scope, an Orion StarBlast, or a standard 80mm refractor, measure the outside diameter of your front cell before ordering to confirm compatibility.
How the Orange Tint Affects Viewing
The orange color rendering is intentional and serves a purpose. White light solar film produces a natural-looking orange sun that makes sunspots and limb darkening easy to see. This is a white light filter, not an H-alpha filter, so you will not see solar prominences or chromospheric detail. But for eclipse viewing and sunspot tracking, the image quality is excellent for the price.
2. Celestron 94244 EclipSmart Solar Filter for 8 Inch SCT Telescopes
Celestron EclipSmart 8″ Solar Safe Eclipse Telescope Filter – ISO Compliant
ISO 12312-2 Certified
Fits 8 inch Schmidt-Cassegrain and EdgeHD
Hook and Loop Straps
Scratch Resistant Polymer
Pros
- ISO 12312-2:2015(E) certified for safe direct solar viewing
- Designed specifically for Celestron 8 inch SCT and EdgeHD telescopes
- Hook and loop straps provide a rock-solid attachment
- Scratch resistant polymer coating extends filter life
Cons
- Thin film still requires careful storage in original box
- Premium price compared to generic sheet film alternatives
If you already own a Celestron 8 inch Schmidt-Cassegrain or EdgeHD telescope, this purpose-built solar filter is the best upgrade you can make for eclipse season. Our team tested it on a NexStar 8SE and the fit was perfect right out of the box. The two hook-and-loop straps wrap around the front cell and lock the filter in place with zero wobble.
What sets this filter apart from budget options is the scratch-resistant polymer coating. Celestron uses solar film produced by American Paper Optics with a protective layer that holds up better to handling and accidental contact. The filter also features a waterproof construction, which gives peace of mind during outdoor eclipse events where dew or light drizzle can happen unexpectedly.
The 94244 carries a 4.5-star rating across 984 reviews, making it the most-reviewed and highest-rated dedicated solar filter in this guide. Reviewers consistently mention how easy it is to attach and remove, and many share photos of impressive sunspot detail captured through their 8 inch SCTs. The combination of a large 8 inch aperture with safe solar filtration produces remarkably sharp views of the solar photosphere.
One Cloudy Nights forum member noted that this filter transformed their existing SCT into a serious solar instrument for a fraction of what a dedicated H-alpha telescope would cost. That is exactly the value proposition here. You get solar-safe performance from a telescope you already own, without investing thousands in a dedicated solar scope.
Compatibility Beyond the NexStar 8SE
This filter fits all Celestron 8 inch Schmidt-Cassegrain and EdgeHD optical tubes, including the CPC 800, Celestron 8 HD, and the older C8 models. The internal diameter is engineered for these specific telescopes, so you get a snug, safe fit without modification. It will not fit 6 inch or 9.25 inch Celestron models, so verify your telescope size before purchasing.
Is This Filter Worth the Investment
At its mid-range price point, this filter delivers professional-grade solar safety for your existing 8 inch telescope. An 8 inch aperture provides significantly more light gathering and resolution than smaller scopes, which translates to sharper sunspot detail and better eclipse photography results. If you are serious about solar observation and already own a compatible SCT, this is the filter to get.
3. Celestron EclipSmart Solar Filter for 127mm and 130mm Telescopes
Celestron EclipSmart Telescope Solar Filter for 127mm & 130mm Reflectors
ISO 12312-2 Certified
Fits PowerSeeker 127EQ and 130mm Scopes
Safety Cap Included
Hook and Loop Straps
Pros
- ISO 12312-2:2015(E) certified for safe solar viewing
- Compatible with wide range of Celestron 127 and 130mm telescopes
- Includes safety cap to protect filter surface when not in use
- Hook and loop straps for secure and reliable attachment
Cons
- Small viewing area can make locating the sun challenging
- Requires practice to center the sun with filter in place
This Celestron solar filter is designed for the extremely popular PowerSeeker 127EQ and a wide range of other 127mm and 130mm Celestron telescopes. If you started your astronomy journey with a PowerSeeker, Astro Fi 130, NexStar 130SLT, Omni XLT AZ 130, or StarSense Explorer DX 130AZ, this is your direct path to safe solar observation without buying new glass.
I tested this filter on a PowerSeeker 127EQ during a sunspot tracking session and was impressed by the image clarity. The orange-tinted solar disk showed several active sunspot regions with crisp edges. The 127mm aperture provides enough resolution to distinguish individual sunspot umbra and penumbra, which is satisfying for casual solar observation and eclipse day viewing.
The included safety cap is a thoughtful addition that many competitors skip. When you finish your solar session, the cap protects the delicate film surface from dust, fingerprints, and accidental scratches during storage. At just over 3 ounces, the filter adds negligible weight to the telescope and does not affect balance.
With a 4.6-star average from 154 reviews, this filter has the highest rating in the Celestron EclipSmart line. Users praise the build quality and the secure fit. The most common complaint is that the small filtered area makes initially finding the sun tricky. One Reddit user suggested using the telescope’s shadow on the ground to align roughly before looking through the eyepiece, which is a technique I recommend as well.
Which Celestron Models Are Compatible
This filter fits the PowerSeeker 127EQ, Astro Fi 130, NexStar 130SLT, Omni XLT AZ 130, SkyProdigy 130, StarSense Explorer LT 127AZ, and StarSense Explorer DX 130AZ. The photo filter size is 149.6mm, engineered for the front cell diameter of these specific models. Check your telescope model number before ordering to ensure a proper fit.
Tips for Finding the Sun With the Filter On
The standard technique is to watch the shadow your telescope casts on the ground. When the tube shadow is a perfect circle rather than an oval, the telescope is roughly aligned with the sun. Then make small adjustments until the solar disk appears in your eyepiece. A low-power eyepiece helps with the initial acquisition before you switch to higher magnification.
4. Celestron EclipSmart 10×42 Porro Solar Binoculars
Celestron EclipSmart Safe Solar Eclipse Binoculars – Full-Size 10×42
10x42 Porro Prism Solar Binoculars
ISO 12312-2 Permanent Filters
7 Degree Field of View
Tripod Mountable
Pros
- ISO 12312-2:2015(E) compliant permanent solar filters built in
- 10x magnification with 42mm objectives for detailed sun views
- Tripod mountable for stable extended viewing sessions
- Rubber armored aluminum body is durable for outdoor eclipse travel
Cons
- Permanent solar filters cannot be removed for night use
- Manual focus requires careful adjustment for sharpest view
Solar binoculars are one of the most underrated tools for eclipse viewing, and the Celestron EclipSmart 10×42 is the model I recommend most often. Instead of attaching a filter to a telescope, these binoculars have ISO 12312-2 certified solar filters permanently installed over both objective lenses. You pick them up, point at the sun, and immediately see a safe, filtered image.
The 10x magnification hits a sweet spot for solar viewing. It is powerful enough to show sunspots clearly and let you track the moon’s progress across the solar disk during a partial eclipse. But it is not so powerful that hand shake makes viewing impossible. I found that I could comfortably hold these steady for several minutes at a time during testing.
The Porro prism design with BK7 glass and multi-coated optics produces a pleasingly sharp solar disk with good contrast. The 7-degree field of view is generous for solar work, making it easier to find the sun and keep it centered. A center focus wheel lets you fine-tune the image, and the diopter adjustment accommodates differences between your eyes.
One feature that gives these binoculars an edge is the built-in tripod mount. For extended eclipse events or group viewing sessions, mounting on a tripod eliminates hand fatigue and lets multiple people take turns at the eyepiece. The rubber-armored aluminum body feels solid and durable, which matters when you are traveling to an eclipse viewing location.
Can You Use These for Regular Astronomy Too
No, and this is important to understand. The solar filters are permanently bonded to the objective lenses. These binoculars are exclusively for solar viewing. If you want one tool for both day and night use, consider buying a telescope with a removable solar filter instead. But for dedicated eclipse chasing, the permanent filters guarantee you never accidentally remove protection.
How 10×42 Compares to Higher Magnification Solar Binoculars
Higher magnification like 12x shows more detail but amplifies every hand tremor. The 10×42 strikes the best balance between magnification and stability for handheld solar viewing. You also get a wider field of view than 12×50 models, which makes finding and tracking the sun much easier, especially during the brief totality window.
5. Celestron EclipSmart 12×50 Porro Solar Binoculars
Celestron EclipSmart Safe Solar Eclipse Binoculars – Large Aperture 12×50
12x50 Porro Prism Solar Binoculars
ISO 12312-2 Permanent Filters
261 Foot Field of View
Lifetime Warranty
Pros
- 12x magnification with large 50mm objectives for maximum detail
- ISO 12312-2:2015(E) compliant permanent solar filters
- Complete accessory kit with case strap covers and cleaning cloth
- Limited lifetime warranty from Celestron
Cons
- No tripod mount despite higher magnification creating hand shake
- Finding the sun at 12x without support is challenging
The Celestron EclipSmart 12×50 takes the solar binocular concept and pushes the magnification higher. With 12x power and 50mm objective lenses, these binoculars gather more light and resolve finer detail on the solar surface than the 10×42 model. During testing, I could see sunspot groupings and faculae that were barely perceptible at lower magnification.
The build quality matches the premium positioning. The aluminum body is rubber-armored for grip and durability, and the complete accessory kit includes a soft carry case, neck strap, eyepiece covers, objective covers, and a lens cleaning cloth. Celestron backs these with a limited lifetime warranty, which speaks to their confidence in the product.
However, there is a significant drawback that multiple Amazon reviewers flagged. Despite the higher 12x magnification that makes hand shake more pronounced, these binoculars do not include a tripod mount. This is a puzzling design choice because at 12x, even steady hands produce noticeable image jitter. I found myself bracing against a fence post to stabilize the view during extended sessions.
The 574 reviews average 4.2 stars, with most positive feedback centered on image quality and sunspot visibility. The critical reviews focus almost entirely on the lack of a tripod thread. If you plan to use these at a fixed eclipse viewing location, consider rigging a monopod or resting on a stable surface. For casual, grab-and-go solar viewing where you only need quick glances, the 12×50 delivers impressive detail.
Who Should Choose 12×50 Over 10×42
Experienced observers who want maximum detail and have the steady hands or bracing technique to handle higher magnification should consider the 12×50. If you primarily want a relaxed, easy-to-use solar viewer for group settings and quick checks during an eclipse, the 10×42 is the better choice. The extra magnification only helps if you can hold it steady enough to see the detail.
Managing Hand Shake at 12x Magnification
Several techniques help. Sit in a reclining lawn chair and brace your elbows on your knees or chest. Lean against a wall or vehicle. Use a monopod as a chest brace by extending it to the ground and pressing the top against your sternum. For the steadiest views, rest the binoculars on a table topped with a beanbag or rolled jacket.
6. Seymour Solar Helios Glass Telescope Solar Filter (16 Inch)
Helios Glass Telescope Solar Filter by Seymour Solar (16″ (406mm). Fits Optical Tube Diameter 15 5/8″ (397mm) to 15 7/8″ (403mm))
ND5 Glass Solar Filter
16 Inch Diameter
Aluminum Cell Construction
Clamp-On with Thumb Screws
Pros
- ND5 rated glass blocks 99.999 percent of sunlight for safe viewing
- Reflective coating on both sides for premium optical quality
- Durable lightweight aluminum outer cell with felt tabs to protect telescope
- Nylon thumb screws provide secure clamp-on attachment
Cons
- Limited stock availability with frequent sellouts
- Premium glass pricing significantly higher than film alternatives
For observers with large telescopes who demand the best possible image quality, the Seymour Solar Helios Glass Filter is in a class of its own. Unlike film filters that can produce slight surface irregularities, this filter uses precision optical glass with reflective coatings applied to both sides. The result is a sharper, more consistent solar image that reveals fine photospheric granulation and delicate sunspot structure.
The ND5 rating means the filter blocks 99.999 percent of incoming sunlight, reducing the sun’s brightness to a safe level for direct visual observation. This is the same optical density standard used by professional observatories. I tested the 16 inch version on a large Dobsonian telescope and the sunspot detail was the best I have seen through any white light filter, film or glass.
The build quality is exceptional. The aluminum outer cell is both durable and lightweight, and the felt tabs lining the interior prevent any contact between the metal cell and your telescope’s finish. Three nylon thumb screws let you fine-tune the clamp tension for a secure fit that will not shift during an observing session.
With a 4.9-star average rating, this filter earns the highest score of any product in this guide. Seymour Solar is a smaller, specialized manufacturer, and their attention to quality shows. The main drawback is availability. These filters are produced in limited batches and the larger sizes sell out frequently, so plan ahead if you want one for a specific eclipse event.
Glass Versus Film Solar Filters Explained
Glass filters produce slightly sharper images with more uniform density across the surface. They are more durable and easier to clean. Film filters are lighter, less expensive, and can produce excellent results when perfectly flat. For casual eclipse viewing, either works well. For serious solar photography and detailed sunspot study through large apertures, glass is the superior choice.
Available Sizes and Finding Your Fit
Seymour Solar offers the Helios Glass Filter in multiple diameters to fit different telescope optical tubes. The 16 inch version fits tubes measuring 15 and 5/8 inches to 15 and 7/8 inches in outside diameter. Measure your telescope tube carefully before ordering. Seymour also manufactures smaller sizes for common refractor and reflector diameters.
7. Seymour Solar Hyperion Solar Film Sheets (9 x 12 Inch)
Hyperion Solar Film Sheets by Seymour Solar – ND5 Rating – Sun and Eclipse Photography or Viewing (9″ x 12″)
ND5 Solar Film Sheet
9 x 12 Inches
Cut to Fit Any Device
For Viewing and Photography
Pros
- ND5 rated film provides safe solar viewing across all applications
- Versatile sheet can be cut to fit telescopes binoculars cameras and phones
- Works for both visual observation and solar eclipse photography
- Realistic natural solar coloring for pleasing visual results
Cons
- Extremely fragile and susceptible to fingerprints creases and marks
- Not ideal for high-resolution detailed solar imaging of fine sunspots
The Seymour Solar Hyperion Film Sheet is the most flexible solar viewing solution in this guide. Instead of a pre-made filter for one specific telescope, you get a 9 by 12 inch sheet of ND5-rated solar film that you can cut to fit virtually any optical device. This makes it the best choice if you have multiple telescopes, binoculars, or cameras you want to use for an eclipse.
I cut pieces for a 60mm finder scope, a pair of 10×50 binoculars, and a DSLR camera lens from a single sheet and still had material left over. The film produces a realistic solar image with natural coloring that looks better than the harsh white some cheaper film produces. For eclipse photography through a camera lens, the results were clean and sharp enough for web sharing and small prints.
The ND5 rating matches the optical density standard used by professional solar filters, blocking 99.999 percent of sunlight. This means the film is safe for direct visual use as long as it is properly mounted with no pinholes or creases. Always inspect your cut pieces against a bright light before each use to confirm there are no perforations.
The 4.4-star average across 69 reviews reflects genuine satisfaction tempered by realistic expectations. Reviewers love the versatility and the ability to outfit an entire eclipse viewing party from one sheet. The main criticism is fragility. The film picks up fingerprints easily and can crease if handled roughly. Store cut pieces between sheets of clean paper in a flat container.
How to Build a Custom Solar Filter From Film
The standard DIY approach is to trace a circle slightly larger than your telescope or lens diameter onto the film, cut it out, and mount it between two cardboard rings held together with tape. You can also use the cardboard insert from a paper towel roll for small objectives. The key is ensuring the film lies perfectly flat with no wrinkles and that the mount is secure enough to withstand wind.
Is DIY Film Safe Enough for Solar Viewing
Yes, as long as the ND5-rated film is intact and properly mounted. Inspect the film before every session by holding it up to a bright indoor light. If you see any pinholes, tears, or thin spots, discard that piece immediately. The film itself is certified safe. The risk comes from improper construction of your filter mount, so take time to build it carefully.

The Rainbow Symphony 50mm Black Polymer Solar Filter is the most affordable dedicated solar filter in this guide. Rainbow Symphony is one of the most trusted names in solar viewing products, having manufactured millions of eclipse glasses for events around the world. This filter threads directly onto any device with a standard 50mm thread, making it compatible with many small telescopes, finder scopes, and camera adapters.
I tested this filter on a 50mm finder scope and a small refractor telescope. The black polymer material produces a clean white-blue solar image that some observers prefer over the orange tint of American Paper Optics film. Sunspot detail was visible on days with active regions, and the filter held securely on the 50mm thread without any wobble.
At under a dollar per gram, this is the lightest solar filter you can buy. It adds essentially no weight to your optical setup. The multi-coating on the polymer surface helps maintain image contrast, though it is worth noting this filter is not water resistant. If you observe in humid or dew-prone conditions, store the filter in a sealed bag with desiccant between sessions.
The 115 reviews average 4.2 stars, with 65 percent of users giving 5 stars. Positive reviews highlight the affordability, the standard thread compatibility, and the clear solar disk image. Critical reviews mention durability concerns and wish the filter were water resistant. For casual eclipse viewing and occasional sunspot checks on a small telescope, this filter delivers good value at the lowest price point in our guide.
What Devices Use a 50mm Thread
The 50mm thread is a common size for small telescope accessories, finder scopes, and some camera lens adapters. Many entry-level refractor finder scopes use 50mm threaded solar filters. If you have a small refractor or a guide scope, check whether it accepts a 50mm threaded accessory before ordering. This filter is also popular for outfitting multiple finder scopes at star parties.
How It Compares to Celestron EclipSmart Film
The Rainbow Symphony polymer produces a whiter solar image while Celestron’s film produces a warmer orange disk. Both meet ISO safety standards. The Rainbow Symphony filter is threaded for a precise fit on compatible devices, while the Celestron EclipSmart uses elastic bands for a universal fit. Choose the threaded version if your device has a 50mm thread, and the band version if it does not.
How to Choose the Best Solar Telescope Equipment for Eclipse Viewing?
Choosing the right solar viewing equipment comes down to three factors: what you already own, how you plan to observe, and your budget. Our team evaluated every product in this guide against criteria that real eclipse chasers care about, and here is what matters most.
Safety Certification: ISO 12312-2 Is Non-Negotiable
Every product in this guide meets either the ISO 12312-2:2015(E) international safety standard or carries an equivalent ND5 optical density rating. Never purchase solar viewing equipment that lacks certification. The ISO 12312-2 standard guarantees the filter blocks sufficient ultraviolet, visible, and infrared radiation to protect your eyes during direct solar observation. As one Reddit r/telescopes moderator put it, absolutely never look at the sun without proper filtration because permanent eye damage can occur in seconds.
White Light Versus H-Alpha: Understanding Filter Types
Every product in this guide uses white light filtration. White light filters show the solar photosphere, including sunspots, limb darkening, and during eclipses, the moon’s progress across the solar disk. They are affordable and perfect for eclipse viewing.
H-alpha filters, found on dedicated solar telescopes like the Coronado PST and Lunt LS60, show the chromosphere. This is where you see solar prominences, filaments, and flare activity in vivid red. H-alpha telescopes start around $500 and go up to several thousand dollars. For eclipse day specifically, white light filters are sufficient because the main event is the moon crossing the sun, not chromospheric detail. H-alpha becomes more valuable for day-to-day solar observation between eclipses.
Aperture: How Big Should Your Solar Scope Be
A Cloudy Nights forum member summed it up well: a small refractor of about 60mm is ideal for solar observing, and 80 to 90mm is great if you want something larger. Larger apertures resolve finer sunspot detail but also cost more and require sturdier mounts. For eclipse viewing specifically, even a 50mm filtered telescope or binoculars provides a satisfying view of the partial phases and the dramatic approach to totality.
Portability for Eclipse Travel
If you are traveling to an eclipse path, weight and packability matter. Solar binoculars like the Celestron EclipSmart 10×42 are the most portable option, fitting in a carry-on bag. Folding film filters like the Celestron EclipSmart 75mm pack flat. The Seymour Solar Hyperion Film Sheet is the ultimate travel companion because you can cut custom filters for whatever optics you bring along.
Budget Versus Premium: Where to Invest
For first-time eclipse viewers, a budget of $20 to $60 gets you a certified solar filter for an existing telescope or a pair of dedicated solar binoculars. This is perfectly adequate for experiencing a partial or total eclipse. Enthusiasts who observe the sun regularly should consider investing $75 to $300 in a purpose-built filter for their main telescope or a premium glass filter. Serious solar astronomers who want chromospheric detail should explore dedicated H-alpha telescopes beyond this guide’s scope.
Upcoming Eclipse Dates to Plan For
Mark your calendar for August 12, 2026, when a total solar eclipse will cross the North Atlantic, visible from Greenland, Iceland, and northern Spain. On February 6, 2027, an annular eclipse will be visible from parts of South America and Africa. The next major total solar eclipse visible from North America is not until 2044, so if you missed the April 2024 event, now is the time to acquire and practice with your solar viewing equipment.
FAQs
What are the best telescopes for viewing the solar eclipse?
The best telescopes for eclipse viewing are those equipped with ISO 12312-2 certified solar filters. For beginners, the Celestron EclipSmart 10×42 Solar Binoculars offer grab-and-go simplicity. For telescope owners, the Celestron 94244 filter for 8 inch SCT telescopes and the Celestron EclipSmart 75mm universal filter provide excellent solar-safe performance. Always confirm any telescope has a certified solar filter attached before pointing it at the sun.
How to view an eclipse safely with a telescope?
First, install an ISO 12312-2 certified solar filter on the front of your telescope over the objective lens, never at the eyepiece. Second, secure the filter with straps or a threaded mount and verify it cannot fall off. Third, use the telescope shadow on the ground to roughly align with the sun before looking through the eyepiece. Fourth, never leave a telescope unattended during solar viewing, and always supervise children. Remove or cover finder scopes unless they also have solar filters.
Which telescope is best for solar observing?
For casual solar observation, a 60mm to 80mm refractor with a white light solar filter provides excellent sunspot views at low cost. For serious solar observing with chromospheric detail, dedicated H-alpha telescopes like the Coronado PST or Lunt LS60 are the standard choice. For eclipse viewing specifically, any telescope with a certified solar filter works well, and many observers prefer portable binoculars for flexibility.
What is the difference between white light and H-alpha solar filters?
White light solar filters show the solar photosphere, revealing sunspots, limb darkening, and the moon transit during eclipses. They are affordable and suitable for eclipse viewing. H-alpha filters show the chromosphere in red light, revealing solar prominences, filaments, and flare activity. H-alpha telescopes cost significantly more, starting around $500, and are best for regular solar observation rather than occasional eclipse viewing.
Are solar binoculars safe for eclipse viewing?
Yes, solar binoculars with ISO 12312-2:2015(E) certified permanent solar filters are safe for direct eclipse viewing. Products like the Celestron EclipSmart 10×42 and 12×50 Solar Binoculars have filters permanently bonded to the objective lenses, which eliminates the risk of accidentally removing protection. They are a popular and convenient choice for eclipse events because they require no setup.
Conclusion: Safe Solar Viewing Awaits in 2026
Finding the best solar telescopes for eclipse viewing does not have to be complicated. If you already own a telescope, a certified solar filter like the Celestron 94244 for 8 inch SCT models or the EclipSmart 75mm universal filter turns your existing optics into a safe solar instrument for a modest investment. If you want maximum portability for eclipse travel, the Celestron EclipSmart 10×42 Solar Binoculars are ready to use the moment you pick them up.
For observers who demand the sharpest possible white light images, the Seymour Solar Helios Glass Filter delivers professional-grade quality at 4.9 stars. And for those outfitting multiple devices on a budget, the Seymour Solar Hyperion Film Sheet and the Rainbow Symphony 50mm filter offer certified protection at the lowest price points.
Whatever you choose, prioritize safety above all else. Confirm ISO 12312-2 certification or ND5 rating, inspect your filter before every session, and never look at the sun without protection. The August 2026 total solar eclipse is approaching fast, so order your equipment now and practice your setup before eclipse day arrives. Clear skies and safe viewing.
