The AG Optical Systems 17" F6.7 Imaging Dall Kirkham (iDK) astrograph is an observatory-class quality imaging instrument featuring a huge 60mm flat field free from astigmatism and coma. The outstanding optical performance of the 17" iDK is made possible through the use of an integral, permanently aligned field corrector combined with a high quality Dall Kirkham F6.7 optical system. Wide field images are captured with high-contrast details and sharp stars across the entire field of view.

AG Optical Systems is introducing in 2019 a .75x reducer that enables the 17" iDK to operate at F5. The reducer offers 90mm of back focus with a corrected 40mm field of view. With the addition of the .75x reducer, owning an AG Optical Systems 17" iDK is like having two telescopes in one.

Here are some details on our premium 17" Imaging Dall Kirkham F6.7 astrograph:

- Premium 17" imaging telescope with low expansion optics
