What people say
The 60F refractor provides a perfectly flat field that makes stars look like pinpoints to the very edge.
The N210 is a light-gathering powerhouse that has cut my exposure times down significantly.
The build quality of the 71F is excellent, and the quadruplet design handles color correction beautifully.

Askar Questions
What is an astrograph?
An astrograph is a telescope specifically designed for astrophotography. These models, like the N160 and 71F, focus on providing a flat field and fast light collection for cameras.
What kind of glass do the refractors use?
The refractor models in this catalog use ED (Extra-low Dispersion) or SD glass. These materials are essential for professional quadruplet APO designs to ensure color accuracy.
How do the reflector models differ from the refractors?
The reflectors, such as the N210, are Newtonian astrographs with very fast F3.4 ratios for deep-sky work. The refractors are quadruplet air-spaced designs that prioritize a flat field.
Are these telescopes ready to mount?
Yes, these models include Vixen-style dovetail plates (ranging from 160mm to 230mm). This allows them to be easily attached to most standard astronomical mounts.
