FARPOINT Bahtinov Telescope Focusing Mask for Celestron 8" SCT Telescopes with Hyperstar

Drop-in focusing mask for 8" SCTs (Schmidt Cassegrain Telescopes) when used with a Hyperstar.
Focusing tool for serious astrophotographers and those who care about their time and quality of astrophotos.

8" MEADE OWNERS!

Please note, there are three versions now, one for Celestron (FP410), another one for also Celestron C8 (FP410H) with Hyperstar and one more for Meade (FP411), because the Meade tube is tiny bit smaller, so basically the Celestron version won't fit the Meade, but the Meade would fit the Celestron. Therefore if we are out of stock of the Celestron version, we might send you the Meade version instead. (This won't work the other way around though...)

Also, this version is generally for C8 owners who might one day use a Hyperstar as this version has got a slightly larger central opening, app. 78.1-78.3mm diameter.

CELESTRON 8" EVOLUTION OWNERS!

Please note, the size of the secondary mirror holder is about 70.32mm and the inner diameter of the Bahtinov is about 70.0mm, so the normal FP410 might be just shy of that not big enough and the Hyperstar version might be too big (not that that should be a real problem), so for Evolution 8" users we'd recommend to buy either this version (FP410H), or if you decide to buy the FP410, then please call us and we will get it up to the right size with a deburring tool... Thanks.
