Product description

ASKAR is a line of select telescopes for astrophotography. These telescopes place great emphasis on optical, as well as mechanical quality. The product designation FRA stands for a refractor telescope with integrated corrector element for a flat and corrected field of view. The FRA series is mainly used for astrophotography.

The ASKAR FRA300 is a 5-element Petzval apochromat with 300 mm focal length, f/5 and 60 mm aperture. There are 2 ED glasses built into the lens for good correction of chromatic aberration. The apo is corrected for cameras up to full frame sensor.

The dew shield also provides good protection against stray light and is retractable. The large focuser holds heavy cameras and the dual-speed gear allows precise focusing. T2, M48 and M54 threads are available for connections. The working distance is optimized for all popular cameras, from mirrorless system to DSLR to astro cameras (CMOS and CCD).

A photo specialist, but also suitable for observation:
The ASKAR FRA300 was designed for astrophotography. The working distance from the connection threads is not designed for observing with 2" star diagonals or prisms. With a T2 diagonal prism with short light path and good Plössl eyepieces you can focus and make very nice observations as well.
