Amazing Televue 1.25 Inch Eyepiece Adapter For Questar Field Version Maksutov Telescope

In this video I have used these eyepieces: Televue Ethos 13mm 100 Degrees Eyepiece. Televue Panoptic 24mm 68 Degrees Eyepiece. Brandon 24mm 52 Degrees Eyepiece. Getting the Most From Your Questar 3.5 The aperture opening in Questar eyepiece holder limits the true field of view in eyepieces with large field stops. However, compared to the 24mm Questar supplied eyepiece, the Tele Vue 19mm Panoptic has 17% wider true field and the 24mm Panoptic has a 30% wider true field, even with vignetting limiting its potential. Overall, we recommend the Delos 10mm and Panoptic 19mm. While all 1¼" TVO 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.
