The AG Optical Systems Convergent Fast Astrograph .5 meter (20 inch) F5 telescope is an observatory-class imaging instrument featuring a huge 60mm flat field free from astigmatism and coma. The outstanding optical performance of the FA20 is made possible through the convergence of careful design, state-of-the-art manufacturing, and precise assembly. Wide field images are captured with high-contrast details and sharp stars across the entire field of view.

Product Description

AG Optical 20" Convergent Fast f/5 Astrograph

The AG Optical Systems Convergent Fast Astrograph .5 meter (20 inch) F5 telescope is an observatory-class imaging instrument featuring a huge 60mm flat field free from astigmatism and coma. The outstanding optical performance of the FA20 is made possible through the convergence of careful design, state-of-the-art manufacturing, and precise assembly. Wide field images are captured with high-contrast details and sharp stars across the entire field of view.

The AG Optical Systems FA20 F5 optical system provides exceptional thermal stability. Low expansion optics ensure the figure and focus stability of the Convergent FA20 as the temperature changes over the course of an imaging session. When combined with the rigid, thermally stable carbon fiber truss tube assembly of the FA20 you can expect to spend less time focusing and more time collecting data.

AG Optical Systems FA series carbon fiber truss optical tube assemblies make extensive use of carbon fiber composite materials, CNC-machined components, and precision collimation adjustments to provide a rigid and thermally stable platform for the low expansion optics. Three cooling fans speed the cooling of the primary mirror while primary and secondary mirror heaters can be automatically controlled by the optional Thermal Control System (TCS).

The optional, robust, digital Optec Gemini rotating focuser is ASCOM-compatible is capable of precision focusing and rotation while carrying heavy CCD imaging trains.
