Average User Rating

Televue Questar Adapter AQE-0005

Just add this adapter to use any of the Televue 1.25" eyepieces: Plössls, Radians, Panoptics and Naglers! Experience a greater range of magnification and quick-change capability.

Discover improved resolution, color correction and contrast due to the multicoating, blackened lens edges, and new designs.

TeleVue Questar Adapter


This finely crafted piece is CNC-machined out of solid aluminum stock to complement the Questar. Its polished aluminum base has blackened anti-reflection threads on the inside aperture to improve contrast. A black anodized knurled focusing ring allows focusing to the Questar viewfinder optics, and a lock screw (with 2 locations for convenience) gives extra security.

The threaded eyepiece barrels accept Nebular and other filters, if desired. And, with fields of view up to 82 degrees, diffraction limited anywhere in the field, your Questar 3.5 finally delivers the magnificent capability inherent in its design and construction. Overall, we recommend the Nagler 9mm and Panoptic 19mm. While all 1.25" Televue eyepieces can be used with the Questar, only the following will focus in the finder mode and offer parfocalization (no need to adjust focus when changing eyepieces) as well:

  • Plössl 32*, 25, 20, 15, 11 & 8

  • Panoptic 24*, 19 & 15

*Questar opening limits the field of the 32mm Plossl and 24mm Panoptic
