    Questar Adapter is rated 3.7 out of 5 by 3.
    Rated 5 out of 5 by from Works well You need to understand that this adapter is for the top visual port, not the back (straight-through) axial port. Unscrewed the visual port and this adapter screws in just fine. Nice quality and looks exactly like the other aluminum finish on the back of the Questar. The set screws on this adapter are the 6-32 (I think it is a coarse UNC type??). Went to local home improvement store and bought two 6-32 x 3/8 socket head cap screws (there are two holes on the adapter you can use, why not use both??). Eyepieces fit fine and I can have both screws holding them in place. Note: the 4mm screws will not fit, must be 6-32.Have not used the tunable top to fine-tune the eyepiece focus, but that may come in handy if I do any close-up or more critical astro stuff.B&H price is fair and cheaper than anywhere else. Expedited shipping was a nice touch.

    Rated 1 out of 5 by from Nicely Machined, but it doesn't fit. The Televue adaptor doesn't fit my Questar 3.5, and I'm sure mine is a typical Questar, being a circa 1972 scope. The threaded part of the adaptor is simply too small to screw into the scope. The part of the adaptor that is supposed to thread into the scope has an outside diameter of about 15/16, whereas the corresponding threaded part of the scope is well over one inch in diameter. Close to 1.25, in fact. Mmore than a disappointment, this is a mystery. How could Televue not see this?

    Rated 5 out of 5 by from Well built, fits BOTH ports I am a professional astronomer (now retired!) and do public reach-out for astronomy. Use this device with video output for larger audiences. Works great!
