Orion Glass Solar Filter for scopes with 5.5" outside tube diameter, part number 7731. It fits Orion's Sky View Deluxe 4.5" reflectors, Orion/Vixen VX102 refractors, and many other scopes of similar diameter. (It will fit scopes as small as 5.25" diameter by adding the included foam tape.)
This filter has been used about 6 times and includes the original box, paperwork, and foam tape (which I never used). New from Orion, the filter sells for $62.95 (on sale) plus $9.95 shipping. This one is in excellent condition for $40.00, including shipping.
I should specify that the filter coating is not 100% flawless: There is a single tiny pinhole (about 1 mm diameter) in the reflective coating on the outer surface. However, the inner surface is in perfect shape, and the pinhole has no discernible effect on views through the filter. (In fact, the instructions that came with the filter indicate these pinholes are common in glass filters, and that they can be masked with a black marker without any loss of resolution.)
Also available: 4.5" Sky View Deluxe Reflector OTA. (See my ad under Telescope-Reflectors.) If you buy both together, I'll take $10.00 off the total price.
I will mail the filter within one business day of receiving a money order or cashier’s check. I will accept personal checks, but will delay shipment for one week to give them time to clear the bank. Sorry, no international shipments. Please email me with any other questions. Thanks!
