Askar FMA230 Guide Scope/Lens
This 50 mm aperture guide scope from Askar is small and versatile. The front objective lens configuration is a triplet, with a 50 mm diameter, a 275 mm focal length, and a focal ratio of 5.5. Two of the lenses are made of extra-low-dispersion (ED) glass to minimize chromatic aberration. The tube is equipped with a large, helical focuser for precise focusing.
The included 0.84x reducer houses an additional four-element lens configuration. When combined with the front objective lens, this produces a system with a 230 mm focal length, a focal ratio of 4.6, and a backfocus of 55 mm.
Included is the FMA230 with reducer, two tube rings with Vixen-style bracket, a carrying handle/dovetail, a 2" adapter, and an information sheet. An eyepiece (sold separately) is required for visual use, in conjunction with the included 2" adapter. The detachable handle can be installed on the top side of the tube ring and doubles as an additional dovetail to connect additional accessories.
