Astrograph Askar 130PHQ Quadrupole APO
The 130PHQ is a long focal ratio flat field astrograph recently released after the 107PHQ. Instead of buying additional flatteners, there is no need to calculate back focus. Just set up your camera, focus and the star correction will be maximized
High quality imaging optics:
130PHQ has a 23mm larger aperture than 107PHQ. The 130PHQ has a focal ratio of f/7.7, which is longer than the f/7 of the 107PHQ, and a focal length of 1,000 mm. The quadruple Petzval lens with two ED crystals offers excellent control of chromatic and other aberrations. With its self-bleaching design, the 130PHQ offers great advantages in astronomical photography.
Supports a 60 mm image circle,
The Askar 130PHQ is a true all-rounder at f/7.7 - it is designed as a telescope for almost any application:
With a focal length of 1,000 mm and a large corrected field of view, imaging of large objects is possible. But also fine details of objects can be brought out when using high-resolution cameras.
Using different cameras with different flange focal lengths is not a problem. Concentrate and you're always at the right distance. The battle of adapters is eliminated.
The focus has a long travel, so you can find the focus without any problems.
The working or back focus distance from the 2" receptacle is long enough to use 2" star diagonals. This turns the apo flatfield into a wide field telescope or even a planetary telescope, depending on the eyepiece used.
