Telescope Name: Convergent FA12
Telescope Price: $10,495
Item #: CFA12
The AG Optical Systems Convergent Fast Astrograph .3 meter (12.5 inch) F5 telescope is a semi-portable imaging instrument featuring a 50mm imaging circle The outstanding optical performance of the FA12 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 FA12 F5 optical system provides exceptional thermal stability. Low expansion optics ensure the figure and focus stability of the Convergent FA12 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 FA12 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 anti-dew heaters can be automatically controlled by the optional Thermal Control System (TCS).
The optional, robust, digital Optec Gemini rotating focuser is ASCOM-compatible and is capable of precision focusing and rotation while carrying heavy CCD imaging trains.
