The Mini Borg scope provides a solid base upon which very compact and stable guide scope systems may be built. The Mini Borg 50 features a high quality achromatic doublet objective (optics made in Japan) with a focal length of 250mm (f/5).
The Mini Borg guide scopes are much lighter than other scopes, an important factor contributing to an imaging setup which does not suffer differential flexure, whether mounted in piggy-back or side-by-side configuration:
Mini Borg guiders can be selected with a sliding drawtube forcuser, or alternatively with a precision helical focuser to insure that all connections in the guider system are threaded and rigidly coupled to eliminate the guide scope flexure problems common with heavy guide cameras.
