ASKAR FMA230 50 mm f230 mm f/4,6

Askar FMA 230 Professional-Grade Astrograph for Astrophotography & Visual Observation

The Askar FMA 230 is an advanced astronomical optics system designed for both astrophotography and visual observations. Its modular design allows for easy transition between these two applications, making it a highly versatile tool for astronomy enthusiasts.

At the core of the Askar FMA 230 is its superior lens system, featuring a three-element apochromatic triplet with an air gap. This precision-crafted lens is designed to offer exceptional correction of chromatic aberrations, thanks to its two elements made from low-dispersion glass (ED). When paired with the four-element focal length reducer, the setup allows for imaging at a focal length of 230 mm with an aperture of f/4.6.

Whether you are capturing stunning astrophotographs or exploring the night sky visually, the Askar FMA 230 excels in both areas. For visual observations, simply remove the reducer and use the included adapter to attach two-inch eyepieces or angle adapters.

For a secure and stable setup, the included mounting clamps feature a robust Vixen foot, ensuring the astrograph is securely mounted. Additionally, the accessory socket is compatible with traditional photographic tripods using an Arca-Swiss connector.
