Celestron 94243 EclipSmart Solar Eclipse Telescope Filter – ISO 12312-2 Compliant, Secure Fit with Solar Safe Film, Works with 6” Schmidt-Cassegrain Telescopes, Black

This product works well. It fits my CPC 800 perfectly. It come with Velcro tabs for safety backup but it fits very positively, snapping in place. The only negative is that it is a fairly thin film of plastic so keep the original box to keep it stored in. If you left it out it could be torn if miss treated. The box fits nicely. Viewing was fine.

The filter works well with my Celestron 8SE and was easy to install. Protects your eyes from solar damage.

fits well and quality is good. Have to be extra careful handling it since it’s a mylar type of film.

I got my little C-5 at a pawn shop, so I didn’t know when it was manufactured. I have a Nexstar 11 so I thought I might use the C-5 for solar viewing, this filter says it fits a C-5 so I bought it. Unfortunately it doesn’t fit my C-5. Celestron clearly says it doesn’t fit C-5 from 2007 or earlier. MY MISTAKE, not the products.

I didn't bother to use the velcro adhesives as there is a retention springy element to the bezel that naturally grips the telescope. Image quality of the sun is great. The lens is solar foil, so I'll be keeping mine in the cardboard box that it came in. The box is thick enough cardboard and compact enough to reasonably do this for a long time.

The shipping was fast and the filter arrived undamaged. The filter was very easy to use and attached similar to the protective cover that comes with the telescope. The images produced from the filtered scope were very nice and I was happy with them for my first attempt at solar photography.If you have a Celestron telescope, this is one of the cheapest and easiest option that you can buy. I am sure you can make a filter out of film sheets, but this is an out of the box option that is ready to go and attaches easily.

Great for astronomers

I am no beginner in astronomy, and observing the sun. I started out back in high school, eons ago, observing the sun, and charting the sunspots, by hand drawing the sun, and the solar storms, as they traversed the sun, day by day.But I had just a small, refracting telescope, with a 3 and a half inches lens and around a 900 mm's tube.And I just used a standard, screw on sun filter, which went on the eyepiece.But I got excellent images, out of that basic setup. But now, with an high quality, sophisticated, 8 inch Schmidt Casstlegrain telescope, this filter is so dark, and murky, it is useless to me.So don't waste your money! Sadly though, I waited too long to return it.
