I have an Ultra Low Profile Helical Focuser that came off my old Newtonian. I bought this many years ago, from a company in Texas, but I haven't seem them advertised in years. It's for 1.25" eyepieces, has 2" of useable focus range, is extremly light weight (all aluminum) and works smoothly. The anodizing on the base plate, for some reason, is a little off color, but that's the only short falling. Anyway, I'm not sure what it's worth, so I'll say $25.00 is a reasonable price for this, and I'll ship it anywhere in the USA. I take certified checks, money orders, or PayPal (preferred). Thank you and clear skies!
