Großer Off-Axis-Guider

It works as expected and I'm happy with it. Shipped quickly. It eliminated the vignetting I had with the L model when used with a Ritchey Chretien. However, there is some important information missing: a warning that the backfocus of this OAG requires a guide camera or an extended planetary camera to be compatible with the focusing system. There is a fixed 10 mm element between the focusing part and the OAG ring, which unfortunately prevented me from using the GM3 664c that I had previously used with the OAG L. Fortunately, I had a guide camera available. This is a shame because with the wider prism, I would have liked to have a wider sensor such as the GM3 664C.
