The AG Optical Systems 10" Imaging Dall Kirkham (iDK) astrograph is a 28 lbs. ultra-portable, premium quality imaging instrument featuring a 50mm flat field free from astigmatism and coma. The outstanding optical performance of the 10" iDK is made possible through the use of an integral, permanently aligned field corrector combined with a high quality Dall Kirkham fused quartz optical system. Wide field images up to 1.7 degrees can be captured with high-contrast details and sharp stars across the entire field of view.

AG Optical Systems Imaging Dall Kirkham 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 fused quartz 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 AG Optical Systems 10" iDK F6.7 optical grade fused quartz optical system provides exceptional thermal stability. Ultra-low expansion fused quartz optics have 1/6 the coefficient of thermal expansion compared to the Borosilicate glass used in other telescopes. Improved optical thermal stability enhances the figure and focus stability of the AG Optical Systems 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.

Here are the details:

- Hand-figured optical grade fused quartz optics by Terry Ostahowski, tested as a system using rigorous interferometry test process

- Proven iDK optical design (APOD winner) with RMS spot sizes (diameter) of 2 microns on-axis to 8 microns 25 mm off-axis

- Carbon fiber truss tube for excellent collimation and focus stability

- Robust, precise, digital Optec TCF-S3i ($1400), Optec Gemini rotating focuser ($3095), or Moonlite Nitecrawler rotating focuser ($2950) options

- Highly portable 24" length with a weight of 28 lbs

- CNC machined, anodized 6061 aluminum components with all stainless steel fasteners

- Primary mirror cooling fans

- Optional Thermal Control System ($975) for automated control of cooling fans and anti-dew heaters (primary and secondary)

- Made-in-the-USA backed by best-in-class customer service

Price: $8,795 OTA plus shipping/crating
