The AG Optical Systems 14.5" F6.7 Imaging Dall Kirkham (iDK) astrograph is a premium quality imaging instrument featuring a huge 60mm flat field free from astigmatism and coma. The outstanding optical performance of the 14.5" iDK is made possible through the use of an integral, permanently aligned field corrector combined with a high quality Dall Kirkham fused quartz F6.7 optical system. 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 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 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.

At AG Optical what you see is what you get; a premium astrograph at a fair price.

Here are some details on our premium 14.5" Imaging Dall Kirkham F6.7 astrograph:

- Premium 14.5" imaging telescope with optical grade fused quartz ultra-low expansion optics (fused quartz blanks, not cheap crystalline quartz blanks)

- Hand figured fused quartz optics precision tested on a double pass interferometer as a system, manufactured by master optician Terry Ostahowski

- Optics provided with test report indicating system Strehl

- Best in class quality 96% reflectivity coatings

- Huge corrected 60mm field of view free of coma, astigmatism, and field curvature with RMS radius spot sizes from 1.3 to 4.4 microns

- Fastest in class F6.7 focal ratio for large field of view and quick integration times

- System baffled for big chip cameras (no baffle retrofits on AG Optical iDK scopes, they were designed as big chip astrographs from the start!)

- Optional Optec TCF-S3i digital focuser ($1400) or Optec Gemini rotating focuser ($3095) with widely available adapters (not expensive customer adapter like the other guy's scopes require)

- Precision carbon fiber truss tube for mechanical and thermal stability

- CNC machined 6061 anodized aluminum components with all stainless steel fasteners (no worries about rust anywhere on AG Optical scopes)

- Proudly made in the USA by a veteran-owned company with USA-made components (including USA-made, interferometrically tested corrector lenses). When you buy an AG Optical Systems telescope you are supporting companies in Alabama, Colorado, Michigan, Missouri, California, Massachusetts, and Georgia.

- Finally, AG Optical Systems is rapidly building a reputation for offering the best customer service in the business both pre- and post sale. Just ask our customers!

Call AG Optical Systems and you will speak to the owner who has designed every optical system in the AG Optical Systems lineup.

The price for our iDK astrographs with fused quartz optics includes carbon fiber truss tube OTA, heavy duty dovetail plate, cooling fans, dust covers:

- 14.5" F6.7 Quartz iDK $15,575 + shipping/crating
