Telescopes

The 10" Newtonian Astrograph from AG Optical features an exterior thermal stable, secure, and lightweight carbon fiber tube and optically has a fast focal ratio, corrected optics, and a large aperture making this optical tube excellent for photography of deep sky objects such as galaxies, nebulae, and star clusters.

The optics inside the 10" Newtonian AG Optical astrograph have a fast focal ratio of f/3.8 coatings. The primary mirror comes with a CATSEYE for collimation purposes.

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.

The 12.5" Astrograph from AG Optical is a lightweight, thermally stable, and fast focal ratio optical tube for the most advanced astrophotographers out there. The astrograph is great for deep sky objects because of its fast focal ratio (f/3.8) and anti-reflective coatings on the mirror. The CATSEYE hotspot in the center is used to aid in collimation.

The 16" Astrograph from AG Optical is equipped with a Wynne corrector, which is excellent for pinpointing stars over 50mm fov. However, 78.5mm of backfocus is also an advantage when using this corrector, which is great for many CCD cameras and other astrophotography accessories.

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.

The 12" AG Optical astrograph has a medium focal ratio of f/6.7 and features an RMS spot size of 6 microns which makes for pinpoint images of stars at low field of views. This optical tube has a two element <0.5% reflective corrector which makes this possible by reducing many of the common light distortions such as coma.

The N-Series Astrographs may be used for three different focal lengths, by using appropriately calculated correctors.
