Product Description

The SVQ100 is a unique four element telescope designed for full frame imaging. It is made on a very short optical tube assembly, well within airline carry-on size limits so you can safely take it anywhere you go. Field is absolutely flat and color correction is virtually “reflector-like” thanks to an advanced optical system using Ohara FPL53 optical glass.

We wanted our quad to be extremely stable to maintain alignment and easily hold the heaviest astro cameras. For this reason, we employ the Feather Touch 3” dual speed, rack and pinion focuser exclusively on this model. The telescope now comes with a threaded camera adapters for both the 42 mm and 48 mm over-sized t-rings. We also have a number of larger adapters available for direct, wide aperture attachment to your full frame camera.

The SVQ is optimized for imaging.  Using a visual adapter the instrument can be used with a diagonal and eyepiece. While the overall visual correction of an astrograph is not the same as a high Strehl apo triplet, the SVQ will work as a flat field “richest field telescope” with excellent color correction. 

We are now shipping the 100Q astrographs. Orders yours now and receive it in only a couple of weeks!

100 mm f-5.8 Quad made with Ohara FPL-53. Includes a 3” Feather Touch focuser, dual hinged mounting rings, and threaded extension. The SVQ100 now comes with both 42 mm and 48 mm t ring adapters. So you can directly thread your t ring equipped camera directly to the focuser. Order now and a $800 deposit will be charged. The balance will be charged when the telescope ships. These telescopes are assembled and triple tested one at a time. They are in continuous production and are shipped on a first come, first served basis. The SVQ100 is shipped in our C17 heavy duty case.
