Unbranded but known by us to have been made by Japanese astronomy equipment maker Mizar (see image of catalog listing) decades ago, a guide scope adjuster for astrophotography. Base measures 2-1/2" x 5", fine adjustment in both axis. Maximum tube diameter it can take is about 3" (between hold down rods). This would be on one side of a large plate that fits onto the top of the mount and allows the fine adjustment of the pointing of the guidescope to match the main scope on the other side of the plate.
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.
