Askar 60F Telescope (87148)

The Askar 60F Flat-Field 60mm 60/408 f/6.8 is a compact four-element apochromatic refractor designed for both astrophotography and visual observing. Its small size and low weight make it an excellent option for anyone seeking a portable instrument with high-quality optics. With its built-in field flattener, the telescope provides a flat field across full-frame sensors without requiring extra correctors or time-consuming backfocus adjustments.

The optical system consists of four elements (three in the front group and one in the rear), including a low-dispersion ED lens. This design ensures excellent chromatic aberration correction and delivers sharp, high-contrast images across the entire field. With a fully illuminated image circle of 44 mm, the telescope is well suited for full-frame cameras and video equipment.

A 2.4" rack-and-pinion focuser with a 1:10 micro-adjustment ratio and a built-in 360° rotator provides precise focusing and easy framing. The package includes photographic adapters with M48×0.75 and M54×0.75 threads, allowing quick attachment of cameras and DSLRs.

The Askar 60F is also suitable for visual use thanks to its 1.25" and 2" adapters. A retractable dew shield improves portability and reduces transport length. The tube features a matte interior finish and multiple finder-scope mounting points on both sides of the focuser and on the handle, offering flexibility when adding accessories.
