Crayford Focuser Single Speed - fit 8" Newtonian. $50
Found this while sorting out lots of very old boxes!
Never fitted, this was purchased new 10+ years ago from Astronomica (Leeds, UK). The intention was to use it to upgrade my vintage 8" F6 AOS newt (now sold). Unmarked new condition. Rubber grips on handles, brass compression rings on both the 2" tube and also the 1.25" adapter. Includes 1.25" dust cap.
The base will fit the curve of a 230mm (9") diameter tube. 70mm profile, 59mm travel, bolt centres are 76mm (3") apart, 5mm width bolt holes. Bolts not included. Weighs in at 715grams, including the 1.25" adapter. Note that this focuser has no visible branding, is single speed, and the travel tube is non-graduated. The tube does have the usual crayford marks.
I think I paid $100+ for this back in the day.
Sell for $50 plus post (or pickup Parkdale, bayside Melb)
Thanks for looking, Dean
