About this product

Model:  askar_fma230

Optical Bench Test

At FLO, we check all our Askar telescopes on an optical bench before dispatch. 

So you can be confident your telescope will have well-figured optics, negligible false colour and spherical aberration, and no astigmatism (the bane of any optical system!). Star shapes will be round, not triangular, oval or egg-shaped!

The Askar FMA230 is a highly versatile ED triplet telescope and camera lens.

The three-element, fully multicoated triplet design includes two ED lenses to enhance contrast and minimise chromatic aberration. 

When used with the supplied 4-element 0.84x reducer/corrector, the FMA230 is a fast, 7-element, highly corrected, F4.6 wide-field astrograph. 

Delivers sharp, high-contrast images when used with a DSLR, mirrorless camera, or astronomy-optimised imaging camera. 

The smooth helical focuser, with M48x.75 thread, has the usual 55mm back-focus distance. 

It is supplied with red anodised aluminium tube rings and a Vixen dovetail mounting plate. 

The mounting rings, Vixen plate, and handle can be removed for use with a DSLR or mirrorless camera for handheld shooting, or when the camera is mounted to a tripod. 

It also includes a convenient carrying handle that doubles as a mount for finders, guide scopes and a ZWO ASiair (all available separately). 

The top of the handle is machined as an Arca-Swiss tripod plate, enabling you to ‘invert’ the scope and mount it easily on a photo tripod. 

When used for visual astronomy at F5.5, the FMA230 also provides wonderful wide-field views. (It includes a 2" eyepiece adaptor plus extensions so can be used with both 2" and 1.25" diagonals).

I tried it for few days now and it was more than what I excepted, good quality, comes with tube rings for easy camera rotation, 2 filter thread with the reducer tube and more. Highly recommended for wide field astrophotography.
