Askar FMA180 pro is an improved successor to the extremely popular FMA180 model, valued for its excellent optical properties, and thus ideal for use as a dedicated astrophotographic lens, professional guider or visual observation instrument
The optical system of the Askar FMA180 pro lens is an apochromatic sextuplet with two low dispersion glass elements. This compact refractor with high light output, flat field and 44mm full illumination disc diameter is the perfect tool for astrophotography with full-frame cameras or camcorders. In the pro version, an additional integrated rotator was used to facilitate the perfect adjustment of the frame, as well as a focusing system with internal focusing.
Another change compared to its predecessor is the 150 mm long Vixen foot present in the pro version, which facilitates the placement of the tube on most mounts, as well as in the sockets intended for mounting the guider. • apochromatic astrophotography lens with an integrated reducer and the possibility of using it as a guiding telescope or for direct visual observations
