Borg 50mm f/5 Achromatic Guide Scope Set for T-Thread Camera w/ XY Positioner
This Borg f/5 Guide Scope for T-threaded cameras features a high quality 50mm objective and 250mm focal length. It provides a solid base upon which very compact and stable guide scope systems may be built.
The X-Y offset positioner is compact, lightweight and 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. 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.
Package includes Mini 50 Objective Assembly, XY Positioner, (2) Extension Tube L, M57/60 Extension Tube M, M57 Drawtube, M57 to M36.4 adapter, TC-XT adapter, and T/T adapter.
