Celestron – EclipSmart Safe Solar Eclipse Telescope Filter – Meets ISO 12312-2:2015(E) Standards – Works with Travel Scope 60 Telescope – Observe Solar Eclipses and Sunspots – Safe, Snug Fit

Purchased for the upcoming solar eclipse. Happy to report that it fits my old 60mm Meade refractor telescope. Many of these old telescopes share dimensions across different brand manufacturers.I ordered the PS60AZ / PS60EQMy Meade Telescope is #226W60mm diameterF = 700mmI removed the visor and used two pieces of cardboard to create a pinhole sun finder, to aid with aiming and prevent any temptation to look towards the sun.I just finally tested it. Sun looks a nice orange color through it. I can make out sun spots.The filter looks almost identical to the stock cap with the smaller aperture to block the heat.Before we got the filter we did a fun project where we projected an image of the sun in a cut out box by removing the eyepiece altogether and using the smaller aperture on the cap.It fits nice and snug just like the stock cap. Still I drilled 3 holes in the dew shield for the screws to secure it on and prevent any accidental removal or bumps.I would have preferred if they had something printed on it to indicate this is the solar filter, and not just a dust cap.

In anticipation of the solar eclipse, I started looking for sun filters. The one I wanted would take 2 weeks to deliver and that would be after the eclipse, so I started looking around.This was described as fitting a Celestron telescope and I have a different brand. My telescope is a 70mm and the Celestron is 70 mm but I didn't realize how different the telescopes can be. Luckily it gave the measurements and it seemed like it would fit so I ordered it.It turned out to fit perfectly; however, the weather didn't cooperate and it was overcast on the day of the eclipse, so I wasn't able to see how it works. So, if you have a different model, it might fit but just make sure you do the meaurements.

These will work to filter the sun if they aren't damaged.I am disappointed that it is just a film attached to plastic, instead of something more durable. If a single spec of sharp dust gets on them, they may be ruined and damage one's eyesight.I am also disappointed that it did not fit my binoculars (ordered size 80 for my size 80 binoculars, but maybe telescopes are measured differently, or this only fits one model?)...I made it work by unscrewing all 3 screws and putting them on the inside. This gave them the small additional length necessary to fit snugly on my binoculars, once tightened using needle nose pliers to rotate the screw heads, which were now pressed up against my binocular housing.

Ordered because I waited to long to order a solar filter. I've been watching this one for awhile but didn't think it would fit. Ordered one last minute out of desperation, figuring I could use my 3d printer to make it work, but no need. It fits snuggly and I can't wait to try it for the eclipse tomorrow. Edit. Added pics to show clarity for an inexpensive filter

Works great for viewing the sun safely with my 70AZ. Seems overpriced for what you get though... just a plastic cap with the same kind of solar film as those cardboard eclipse glasses. For $25 I'd feel better if the filter was made of plastic. The film works, but it's cheap and fragile. One accidental bump and you'd likely ruin it.

Was trying to find a solar filter for my beginner Carson JC-1000 telescope and couldn't find one by Carson but thought I would try this and it fits perfectly. Just be sure to quality check your filter as soon as it arrives. My first delivered had a bend/crease right in the middle so taking photos through this would not be good. Got a replacement quickly that is defect-free.

Wrong size was sent or the description was wrong on the listing. Also didnt come with the instructions as stated in listing. Would have returned it but I accidentally threw the box away. Had to get creative to attach it to the telescope but at least it works as a filter

I was expecting something more robust
