M54 Offaxis Guider for Nikon DSLRs

Maximized stability by avoiding an adjustable guidefinger. With tilt unit and 10mm backfocus. Opimized for Takahashi M54 thread and Nikon DSLRs, incl. T2 guideplatform.

worlds first Off Axis Guider for Nikon with tilting Function

This offaxis guider by Lacerta was specially made to connect Takahashi correctors with M54 thread to Nikon DSLRs. Besides that there is a novel feature: An eventual tilting problem can be adjusted for by 3 screws on the circumference. If you encounter defocused stars on one side of your photo, it is possible to adjust the tilt and get perfect stars to the edge. There are 3 little screws on the circumference that adjust little balls inside the OAG body, which emerge on the front side and are able to detilt the mechanics. The adjustment can be done without taking off the OAG.

The Lacerta OAG is designed to work with fullframe cameras without introducing vignetting by the guide prism.  To adapt different telescopes, two versions ared offered containing different prism sizes.  These are:
