The Askar 107mm 107PHQ astrograph incorporates a four-element optical design to deliver sharp, color-free images for astrophotographers and visual observers. This f/7 astrograph features an air-spaced triplet objective with two ED elements and a field-flattening corrective element further back in the optical path to correct for field curvature over a large 44mm image circle. There’s no need for a separate field flattener – this makes it easy to use this telescope with a wide range of cameras and accessories without being tied to the short back focus of many external corrective elements.

 

 

This premium astrograph includes a large 3.4” rack-and-pinion dual-speed (1:10) focuser that’s fully rotatable through 360 degrees and carries an 8kg load capacity. The focuser includes a removable visual adapter so you can insert a 1.25” or 2” diagonal. It also includes a standard shoe for mounting a finder or small guide scope (both sold separately). With the visual adapter removed, the focuser tube terminates with an M86x1 thread. The scope also includes four stackable adapters for direct attachment of a wide variety of cameras with standard metric threads.
