Hi all, This sounds like a "newbie" question because, well, I am.............to Deep Sky anyway. My question is this; I'm awaiting delivery on a new Moonlite Nitecrawler (2.5in.) and seriously considering either an STX 16803, or an STXL 16200. Will that 2.5in. draw tube be sufficient for those cameras provided the proper threaded adapter is used, rather than a nosepiece?
