Item #: CFA10

The AG Optical Systems Convergent Fast Astrograph .25 meter (10 inch) F5 telescope is an ultra-portable imaging instrument featuring a huge 45mm flat field free from astigmatism and coma. The outstanding optical performance of the FA10 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 FA10 F5 optical system provides exceptional thermal stability. Low expansion optics ensure the figure and focus stability of the Convergent FA10 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 FA10 you can expect to spend less time focusing and more time collecting data.

The Convergent FA10 carbon fiber truss optical tube assembly makes 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
