This is the telescope version of the Pentax 100mm diameter, 400mm focal length lens made for the 67 and 67II cameras. This version not sold in US. Major differences are precision helical focuser with lock and hefty ring-mount for the tube for excellent stability and balance-shifting. Includes tube, mounting, end-caps, Rigel quick-finder Lumicon minus-violet filter, original Pentax aluminum case, adaptor for direct-mounting of Pentax 67 cameras, adaptor for 1 1/4" eyepieces or autoguider and objective-stops for f/4.8, f/5.6, f/6 operation. Many other fittings I've never used. I've used only for astro-photo with Pentax 67 and 67II.
I will pack, insure, and ship UPS ground CONUS for $1,600.00.
