Chuck, I would never consider 17 years of consistently pleasing and sharp images 'vogue' or simply a 'wow' factor. Patient collimation and a great optician are paramount of course. The best planetary images I've ever had have been through Siegfried's Clark, Brent Watson's 10" f/10 newtonian, Dave Bernson's 12.5" f/5 dob and my Cave. I'll keep my amateur astronomer 'baseball cap' on thank you. Dave Bennett P.S. And you thought you'd get through a whole day without ruffling anyone's feathers?! ;-) On Friday, February 21, 2003, at 01:36 PM, Chuck Hards wrote:
Yes, wide-field is a consideration, but that wide-field is hardly even close to diffraction-limited.
If you want performance, you have to set aside "wow" factors and whatever is in vogue at the moment. Put on your engineers hat and take off the baseball cap.

Don't forget considerations of field of view! My 10" f/5 Cave with a 40mm Tele Vue Wide Field gives some very impressive Milky Way shots ;)

Everyone should, unless there is a specific reason for going "short". Of course, legitimate reasons include transportation and ergonomics.
Brent's always been right-on in that department!
