10″ Imaging Dall Kirkham Quartz
Telescope Name: 10″ Imaging Dall Kirkham
Telescope Price: $9,690 with quartz optics/heaters/temp sensors
Item #: 10IDKTCSHO
NOTE: Handles on the back plate can interfere with larger focusers such as the Optec Gemini. Current model 10″ iDK scopes do not have back plate handles.
The AG Optical Systems .25 meter (10 inch) F6.7 Imaging Dall Kirkham (iDK) telescope is an ultra-portable imaging instrument featuring a huge 50mm flat field free of coma, astigmatism, and field curvature. The outstanding optical performance of the 10″ 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 F6.7 iDK optical system provides exceptional thermal stability. Optical grade fused quartz optics ensure the figure and focus stability of the 10″ 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 10″ iDK you can expect to spend less time focusing and more time collecting data.
The 10″ iDK 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. 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, Optec TCF-S3i, or Optec Leo are ASCOM-compatible focusers capable of precision focusing and rotation while carrying heavy CCD imaging trains
NOTE: Handles on the back plate of the 10″ iDK can interfere with larger focusers such as the Optec Gemini. For this reason the handles were removed from the back plate.
