PERFECT IMAGING PERFORMANCE

ASA Astrograph N f 3,6

THE ADVANTAGES AT A GLANCE:
By changing the correctors, "Three telescopes in one"
Fast focal ratio - therefore extremely short exposure times
Stable system because of extremely precise processing




The astrograph of the N-Series have a corrected Wynne corrector with the aperture ratio of f3.6, but they can be converted to a shorter or longer focal length with a few simple steps:
3" Wynne corrector: Focal ratio of f 3.6
2" Barlow corrector: Focal ratio of f 6.8

This means that you have on request a telescope with three different focal lengths.

 
F 3.6 F 6.8  

We produce 16" and 20" astrograph in open truss design. This open design allows for very rapid thermal adaptation to the environment temperature and reduces the tube seeing. The increased the stiffness in these sizes of mirrors by a multiple.
