Used Lumicon 2" Newtonian astronomy telescope helical focuser as shown. Very smooth action and with the length of the removable arms very fine adjustments are a breeze. Curvature of the base matches that of a 10" diameter tube (not the mirror size). Top of drawtube stands 36mm off the surface of the OTA tube, 1.2" of travel beyond that. No 1.25" adapter but they are common, you probably have several floating around in your astro junk drawers. Its thickness will add to the height of course.
WHO WE ARE: Oddog2 is a husband/wife team, home-based small business specializing in the buying/refurbishment/selling of primarily photographic equipment. We do occasionally have other types of things to sell that come to us as a result of our search for camera-related items. We have 47 years of experience (22 years as a hobby, 25 as a full time effort) with photographic equipment, both as a shooter (17 years newspaper photojournalist) and as a collector/restorer/seller. We have been on eBay as Oddog or Oddog2 since September 1999.
