AG Optical Systems
The AG Optical 17" iDK Astrograph is an excellent astrograph for a wide variety of astrophotography. The telescope has a medium focal ratio of f/6.7 with 6 micron RMS spot size. This means that stars appear very pinpoint while still at large field of view.... Learn MoreFREE SHIPPINGModel#: 17IDK(48 States)
A great benefit behind the Dall Kirkham design is excellent off-axis performance. The 12.5 astrograph from AG Optical is in a carbon fiber tub and has a medium focal ratio with a large aperture to support a variety optical and astrophotography combinations....
