1) This collectable 10x40 Unitron finder is actually a long F# small telescope in and of itself. The precision 40mm objective is actually a fine, coated, air-spaced achromat (yes three tiny foil spacers) with diffraction limited performance. At over 14" inches long (you read that right), it really ought to be considered a guidescope.

It comes with the 10x crosshair eyepiece, but you can insert other 0.965" Japanese standard oculars, friction fit for focus. The friction fit adapter is the same as the regular scope ocular holder.

The glass and finish condition is LIKE NEW (except for the two bolted on rings, which naturally have the usual marks set screw marks that are cleverly concealed by the tube rings when mounted--I do not unfortunately still have the tube rings themselves).

$250 shipped in CONUS

2) 36mm dia UNITRON drawtube with threaded-on, friction fit 0.965" ocular adapter. Approximately 9.5" long, in very good condition. Blackened and baffled inside like a small telescope.

$80 shipped in CONUS

3) UNITRON drawtube clamp, accepts the drawtube above and, in turn, has a 40mm dia front opening and bat handle clamp meant to mate the above drawtube to the primary focusing tube, allowing slip focusing behind the rack and pinion. Built like it was meant to last forever.

$50 shipped in CONUS

4) Take it all above for $350 shipped in CONUS, paypal encouraged, no photos, but these are all the orginal equipment standard UNITRON parts you will recognize from their literature.
