The LXD75 is 10" f5 SN. The LX75 is an 8" f10 SCT. The AT6RC is 6" F9. A .5 focal reducer is a bad idea on an f5 scope, but, probably good for an f10 or f9. For a discussion of DSI vs DSLR, see http://cs.astronomy.com/asy/astro_imaging/f/15/p/41073/420955.aspx. It's pretty much a never ending jousting match. From my POV user friendly is the number one issue for intro AP, and a DSLR wins that battle hands down, IMO. I would never recommend a CCD to a novice AP'r. That, admittedly, is a personal choice.
