Askar FMA230 F/4.6
The Askar FMA230 F/4.6 is an extremely versatile, lightweight triplet apochromatic refractor with a focal length of 230mm. The objective lens has an aperture of 50mm and includes two ED (extra-low dispersion) lenses.
The FMA230, when combined with the included quadruplet reducer, is a very capable super wide-field astrograph with minimal chromatic aberration and distortion. As well as its superb imaging capability, it can be configured as a visual telescope, finder or guide scope.
There is 1.25" female thread at the front of the astrograph suitable for all purchasable 1.25" filters and standard M42×0.75 male thread at the back which accommodates most stock DSLR or astronomy cameras (an extra adapter is needed). Our standard configuration includes a tube ring for the installation of Vixen finder base, a 1.25" visual adapter for the attachment of an eyepiece or a guiding camera as well as a high-quality focuser (with thread) and a setting thread to avoid any deviation in astrophotography.
As an ingenious optical design, our FMA135 will definitely offer you a super imaging experience.
