  • Description

DSO imaging cannot live without long exposure, and long exposure cannot live without guiding. To reach more accurate guiding, Askar launches a new 52mm F4 Guide Scope. It is optimized in the structure, providing users with a good guiding ability to achieve better imaging quality.

52mm F4 Guide Scope is light, compact, and stable. With an aperture of 52mm, a focal length of 208mm, and a travel length of 25mm, it weighs only 631g. The design of the doublet objective lens and precise X&Y-axis fine adjustment gives it high accuracy and high stability, offering the users more functions and effects.

The aperture area of the 52mm F4 guide scope is 164% larger than that of the 32mm F4 guide scope, with the increase of light into, the limiting magnitude can reach 10.4. In addition to guiding, the 52mm F4 guide scope can also be used for visual observation.

The helical focusing design is adopted for smooth use. Users can directly turn the focuser manually to adjust. The focuser sets an M3 locking screw hole, more convenient to use. 52mm F4 Guide Scope comes with a 1.25” adapter and an M42 threaded adapter, and a standard Vixen style base and also has a 1/4 threaded hole and an M4 threaded hole on the base for easy attachment.
