Offaxis Guider for Takahashi & Nikon DSLRs
Maximized stability by avoiding an adjustable guidefinger. With tilt unit and 10mm back-focus. Optimized for Takahashi M54 thread and Nikon DSLRs, incl. T2 guideplatform.
Worlds first: Off Axis Guider for Nikon with tilting Function
This off-axis-guider by Lacerta was specially made to connect Takahashi corrector with M54 thread to Nikon DSLRs. Besides that there is a novel feature: An eventual tilting problem can be adjusted by 3 screws on the case housing. If you encounter de-focused 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 case housing that adjust little balls inside the OAG body, which emerge on the front side and are able to de-tilt the mechanics. The adjustment can be done without taking off the OAG.
Optimized for short (S) or long (L) focal ratio
The deflection prism is built in fixed, to avoid the common “OAG diseases” of self-loosening guide fingers, and to control connected reflections or diffraction artifacts. The Lacerta OAG is designed to work with full-frame cameras without introducing vignetting by the guide prism. To adapt different telescopes, two versions ared offered containing different prism sizes. These are:
- S: full-frame cameras with telescopes from f/3,7 to f/7
APS-C from f/2,8 to f/4 (Version “S” means “short ratio”, e.g..: FSQ85 with 0.73 reducer)
- L: full-frame from f/7 to f/15
APS-C from f/4 to f/ 15 (Version “L” means “long ratio”, e.g. Takahashi Mewlon with 0.73x reducer)
