This is a used C11 OTA in excellent condition, with clean optics and a relatively unmarked tube. This is the Fastar model. It includes a number of upgrades:
- Feathertouch focuser (worth $350)
- Bob's knobs (worth $23)
- Top Losmandy plate ($59) with ADM handle ($119) for easy hoisting and mounting
That's over FIVE HUNDRED DOLLARS in added accessories. If you don't like the Feathertouch and/or the Bob's Knobs, the previous owner also left us with the stock focuser and the original collimation screws, which are included with purchase.
It also includes the standard, stock equipment:
- Stock 1 1/4" visual back
- Celestron 40mm Plossl
- Celestron 1.25" diagonal
- 9x50 finder
No packing boxes; this is for in-store pickup only.
