>>>>How about it, people? What's the verdict? I hope that it's favorable, because it would be a lot of fun to own a 6-inch apo refractor with a singlet, BK7 objective lens. -- And if we're going to dream a little here, how about a 10-inch lens? Or even 16 inches? Or --- ???

IMHO the better solution is the zero lens solution. It allows for reasonably fast focal ratios so the tube length is not overwhelming, there is no chromatic aberration to deal with and it allows for viewing the full spectrum or any section you might choose...
