Well, I ordered one of these 6" OTA's this past Saturday night. I've been looking for a 6" f/5 Newt with a 2" focuser for a long time. I want to maximize the aperture and ease of portability and minimize the weight and cool-down time for a grab-n-go scope. I define grab-n-go as one trip out the door, telescope on mount. Anything else is not really grab-n-go.
I also like the image orientation in a Newt: inverted. Ideally, I'd want the natural orientation, but that is difficult to accomplish optimally except for binoculars. I don't like a reversed image as in a refractor+diagonal, Mak or SCT.
The fact that the Woodland Hills vendor verified that these XLT 150's are shipping with a 2" Crayford closed the deal for me.
Looks like I might be selling my 130mm f/5 Newt soon.
Maybe I'll do a three-way shootout among my 6" f/5 Newt, 6" f/12 Mak and 6" f/15 SCT. It's difficult to justify keeping all three now.
