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


Hi Roland,

There definitely will be interest for such an astrograph.  I am certainly interested.  (Problem is that I can't put my hand on a 92 yet.)  Some of those who plan to buy TAK FSQ will turn their heads to an AP 92 if the reducer has full-frame capability.  Furthermore, I would hope that the flattener can produce a 55mm image circle (sharp corner stars, no or very low vignetting) to cover medium format sensors like the Fuji GFX.
