Quality, performance, and service are the driving factors behind every made-in-the-USA AG Optical Systems telescope. We could save money by cutting corners and relying upon mass production techniques for our optics but that is not the AG Optical Systems way. If you want the best performance at the focal plane where it counts, please consider an AG Optical Systems Imaging Dall Kirkham (iDK) telescope .... crafted one at a time by a team devoted to your satisfaction.

The AG Optical Systems 12.5" F6.7 Imaging Dall Kirkham (iDK) astrograph is a premium quality imaging instrument featuring a 60mm flat field free from astigmatism and coma. The outstanding optical performance of the 12.5" iDK is made possible through the use of an integral, permanently aligned field corrector combined with a high quality Dall Kirkham F6.7 quartz optical system. Wide field images are captured with high-contrast details and sharp stars across the entire field of view.

Here are some details on our premium 12.5" Imaging Dall Kirkham F6.7 astrograph:
