About Farpoint FP402

Bahtinov Focus Masks...
• In 2008 an amateur telescope maker and astronomer ppublished an ingenious new way to easily focus your DSLR, webcam or CCD camera for taking astrophotos. The method is simple, very intuitive and the device has universally been named after the inventor. The Bahtinov Mask.

I had one of these for my 5 inch SCT, and this was equally built as well. I like a thick plastic product because it is built to last unlike a DIY type mask. I would recommend these to anyone

Farpoint FP402 Bahtinov Focus Mask

I used it on my 6 inch Astro Tech RC Astrograph. Really worked well on a bright star. Very important to also do another check on a dimmer star for better focus.

Questions about this item:

Shopper  Will this mask work well with a celestron 8i telescope?
ERNEST A  The adjustment screws don't work well for me. Need to attach with painters tape or something. I think they also sell one just for 8 inch SC scopes.
