Perfect for ritchey chretiens
I use this with my rc6 and don't know where I'd be without it. I would recommend at the most spacing it for .72x reduction. Well made and worth the price.
ASTRO-PHYSICS - CCD TELECOMPRESSOR
Very good. shorten my focal length a little but made the optics faster?
So far so good. Only used it once, but I’m very pleased with the results. Cannot wait to get it out again when the weather and moon cooperate.
AP CCDT67 reducer for GSO RC6
Definitely a worthwhile purchase. I got this for my 6" f9 RC and reduced to f6 it's so much faster photographically. My scope has a small bit of curvature at the edges at f9, this is only slightly corrected with the reducer, but the speed increase out ways any cons.
Works on ***** VCM200L
Got this for visual work with a ***** VCM200L and it works. You attached it like a Baader coma corrector to the bottom of the eyepiece. From my reading on Cloudy Nights I understand it also works for CCD work. For a review on the ***** VCM200L see Dakota Starry Nights, Youtube.
