Re: [ap-ug] M33 with 92mm Stowaway, combining RGB, H-alpha, and O-III

It's certainly possible to design and build a super sharp telecompressor for the 92 Stowaway to cover the full frame CMOS cameras with sharp round stars into the corners with no vignetting. It would require 3 things, a more exotic compressor design, a larger focuser and market for it. It would be more or less a super astrograph, rather than a small fun portable scope, plus it would cost more. Is the interest there or not, that is the question.

Tonight I'm shooting in very clear skies, very cold sub-freezing, but poor seeing. Moon is also nearby.

Thanks Roland. I have the 92FF as well.  Just exploring my options. Focal length of 644 vs 488, a 1’x0.7’ delta. That’s worth the trouble of flats for some targets imho. Our skies in Colorado have been terrible so I haven’t had a chance to experiment with the TCC myself yet. I just got it on Monday.
