For Sale
GSO 250mm f8 RC (2000mm focal length)
Selling my trusty 10" GSO Ritchey Chretien due to the purchase of another similar but much higher end RC telescope. This has been a very good imaging scope which is not hard to collimate and holds collimation well. I have been using this with an FLI PDF focuser (see photo for illustration- Note: the PDF is not included in this sale). The over-engineered GSO M115 extension tubes and long backfocus enable a very big imaging train to be connected securely. The optics in this scope are sharp and when collimated will cover an 11K chip quite evenly. Optics are in very good condition.
During my last couple of imaging trips with this scope a few dings and dents have appeared in the metal tube - must've been the mount or something heavy resting on the thin metal tube during transport? The dings in the tube do not affect optical performance but am reducing the price to allow for the cosmetic issues.
Includes the original GSO crayford focuser and the add-on rear cell leveling collar. Additionally, I am throwing in a number of extra 2" extension tubes, and a custom GSO M115 to PDF focuser adapter from Precise Parts. Also includes 6x 3mm spacer washers for getting the effective length of the extension tubes correct for a PDF to reach focus (over $700 in extras). Original shipping box included. Pick up preferred.
Asking $950
(any shipping costs to be paid by the buyer). PMs only please.
thanks for looking
