Up for your consideration is the 2” 2-speed focuser that I swapped out from my Vixen ED100sf in favor of a 2.5” rotatable Stellarvue R&P unit for imaging. This has the Scopestuff FAS2 compression ring visual back installed, with heavy duty thumbscrews to hold your gear securely. I will also include the original 2” visual back with nylon thumbscrews. I adjusted it to hold ~4 lbs without slipping, so the coarse focus is a little on the stiff side, but the fine focus is still quite smooth and turns easily. There are some cosmetic blemishes, but it is 100% functional.
This would be a great upgrade if your Synta-sourced refractor (which might be branded as Skywatcher, Orion, Vixen, or Celestron) has a single speed focuser. It would also be great for a custom telescope build. The critical thing is that this will fit a ~96.7mm ID opening, and is held in place by three (included) screws 120° apart.
I was saving this focuser for a project that I have decided not to pursue. (If you happen to also be in the market for a ~80mm f/15 red glass singlet lens and ~matching cell, let’s talk! :) )
[Sale Pending]
$90, which includes USPS priority mail shipping to U.S. addresses. (I will ship elsewhere if you pay the difference in shipping costs.) For payment, I accept PayPal friends & family (check my feedback if you are concerned about skipping the ‘goods & services’ protections’), Zelle, personal check, money order, or a cash deal in-person (no shipping = discount).
Thanks for looking!
