14.5″ Imaging Dall Kirkham Quartz

The AG Optical Systems .35 meter (14.5 inch) F6.7 Imaging Dall Kirkham (iDK) telescope is an observatory-class imaging instrument featuring a huge 70mm flat field imaging circle free from coma, astigmatism, and field curvature. The outstanding optical performance of the 14.5″ iDK 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 14.5″ iDK F6.7 optical system provides exceptional thermal stability. Optical grade fused quartz optics ensure the figure and focus stability of the 14.5″ iDK 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 14.5″ iDK you can expect to spend less time focusing and more time collecting data.

AG Optical Systems iDK 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. Two 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 or Optec TCF-S3i focuser is ASCOM-compatible is capable of precision focusing and rotation while carrying heavy CCD imaging trains
