In the field of amateur astronomy, it is rare to find an astrograph with a focal length less than 200mm, which is conventionally a speciality of the ordinary cameras. But the ordinary cameras are not specialized for astrophotography, so the images taken by them may not always satisfying.
 
Askar FMA180, a groundbreaking optical device, can reach great sharpness as well as exactly other long-focal-length astrographs.
 
FMA180 is compact with a main tube length of mere 145mm and a weight of 395g. Besides, it can also function as a quality finder or guider.
 
Therefore, the standard configuration contains a pair of tube rings and a finder bracket for practical installation or attachment. The finder bracket can be divided into two parts. One is the the bracket stalk and the dovetail foot for supporting the whole bracket and the other is a dovetail plate which can be disassembled and independently attached to a tripod or other camera tripod heads with the same thread type. The dovetail plate conforms to standard ARCA-SWISS requirement and is carved with corresponding slots and holes for easy connections. The plate is also designed to realize the connection to an equatorial mount with standard Vixen dovetail base.
