If you are looking for an exceptional telescope, one that is the "gold standard" this is your telescope! The reason I am selling this is that we have moved to a home where there is no vista to gaze upon! I'm mobility challenged so trying to go afield is problematic. Price is negotiable- trades for Sonos Arc soundbar or other similar quality. Long regarded (70+ years) as the finest personal telescope in the world, the 3.5” Questar Standard is legendary in its resolution, flatness of field and contrast. Today Questar is known worldwide and has set the highest standard for optical performance. There is no comparison to the usual amateur telescopes, it is astonishing how powerful this scope is. This particular instrument comes with accessory parts such as camera mount adapter (Canon) 2x Barlow, 45 degree prism etc.
