Re: [APML] (OT) IC1396 CCD with Schmidt-like FOV
I was even thinking of the 300mm f/2.8 (Nikon). Modern ones are about as
good as they come, I believe, but still far short of AP refractor
class. If one of these could be produced with such quality I think that
the market potential is very significant - probably most ST-10 owners would
buy one. Steve Mandel would do some nice business out of it too :-)
