Borg Mini Deluxe Guidescope
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.
The X-Y offset positioner allows the CCD camera's sensor to be moved around the guide scope field of view (±12mm X and Y travel) so that the number of available guide stars is maximized. The X-Y offset positioner is compact (120mm x 120mm x 18mm) and lightweight (240g). This approach allows for the flexibility of positioning the guide camera, yet eliminates the need to use 3-point ring systems which are prone to causing flexure problems.
