I too have the exact Knockies (20x80 triplets) that Houghy is talking about (thanks to Houghy) and they are Magic!!!!!!!!
Nebs that are Invisible to scopes just pop out! They are a tad heavy, but that's what mounts are for.
Or for a smaller set, Randall is after a 6" or 8" Dob. Buy him the dob and you keep the Free Knockies that Andrews throw in!
