Could use some sort of handle to remove it - I have had several of these and they work as expected. the best one i have has a thumb tab that makes it easy to remove, otherwise you have to pry up with your finders to get it off the lens. Review: Works after mods, but it didn't fit. - I am another buyer where this piece did _not_ fit. Period. By the time I realized what had happened and managed to pry the thing off of the secondary mirror housing, my collimation was ruined and so was my evening. Wasted a lot of time re-acquiring collimation so I'm not that pleased. But since I did manage to get the mask off without further damage, I modified it based on other Bahtinov mask I have. Once I fixed that, the mask works great and so I am keeping it. Suggestion: Do NOT try to force this down onto the glass of the SCT, if it contacts or rubs against your secondary mirror housing, re-evaluate before proceeding. 1. I opened the center with a round file to reduce contact to the secondary mirror housing. 2. I rigged some soft stops to prevent the piece from dropping down again and wedging against the glass and housing. The stops sit on the glass surface and the mask is flush and square to the mirror, and _just_ _touching_ the secondary mirror housing at the edges. 3. Also wrapped a few pieces of electrician's tape so I can pull it off with equal pressure, as this thing has a tendency to dive down onto the glass when you pull from only one end. Once you get past any fitment issues, the mask works flawlessly and it's part of the kit now. ## Features - Farpoint Bahtinov Mask for the Celestron 8" SCT with Hyperstar / Fastar ready system.

I use it on a Meade SCT-8, an older scope. Opening is ~1/16th more than 4 inches, and OD of the mask is 8 &7/8th inches. Hope that helps. **Q: what is it made of?** A: I have not used it in a long time, but I believe it is a heavy plastic or similar material. **Q: Will this work with an original orange tube early 80's celestron c8?** A: This Bahtinov mask model FP410 will fit pre-2008 Celestron C8 telescopes, so it will fit yours. Post 2008 C8's require the FP410H. Farpoint ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works as expected.
