Testimonial: Die ausgezeichnete Optik und die hervorragende Verarbeitung meines ASA Astrographen, ermöglichten mir einen Standard in der Deep-Sky-Photographie zu erreichen, von dem ich nicht zu träumen wagte. Dr. Antonio Fernandez

 

Astrographs

N-Serie H-Serie
   
N-SERIES
The Astrograph of the N-Series have a
parabolic primary mirror with a focal ratio
of f3.6. with use the 3" Wynne corrector and
corrected a visual field of 50 mm.
The correctors are interchangeable (three
different focal lengths / correctors).
H-SERIES
The astrograph of the H-Series have a hyperbolic primary mirror, which in connection with the system for this calculated corrector smallest possible spot diameter allows. With a focal ratio of f 2.8 and a corrected image circle of 60 mm, they are the ideal instrument for wide-field images.
   

BENEFITS OF ASA ASTRO GRAPHS AT A GLANCE:
Fast focal ratio - therefore extremely short exposure times
Perfect correction over large fields
Use one of the world's best correctors
Lightweight with high quality fiber carbon
Extremely accurate and robust focuser (ASCOM compliant)
Very precise manufacturing tolerances to achieve a stable system



DESCRIPTION:
Basically are the necessary exposure times our Astrograph at a maximum of 600 seconds per frame, because of the extreme luminosity intensity!

All ASA Astrographs are manufactured from superior Suprax glass material and polished to an accuracy of P/V = 1/7 lambda. The coating is an advanced aluminum coating employing enhanced multi layered overcoats to increase the reflectivity of telescope mirrors by an incredible 97% over a wide range of the visible spectrum.
