Quote:Oh yeah, sorry, "5-inch" was a typo. It's the 6-inch. It's being offered for $700 o.b.o. I already have a LXD75 8-inch Newtonian that I use for astrophotography (with a good degree of success). I just didn't know if a refractor with about a 50% longer focal length would give me anything I don't already have. To be honest, I don't really understand the point of refractors, given that reflectors are so much cheaper for a given aperture area. Slightly longer focal length, maybe? Or is there another advantage to them?
