When this adapter is paired with the Celestron Off-Axis Guider, these two imaging accessories allow you to use the full image circle in our larger scopes. Prepare to produce a larger area of illumination for your 9.25”, 11” or 14” Schmidt-Cassegrain or EdgeHD telescope by using this adapter. This configuration is especially helpful to owners of larger format cameras, such as the ZWO ASI6200MM, QHY 600M, or Canon EOS Ra, since their full-frame can take advantage of the more substantial area of illumination produced by larger optical tubes.
The Large SCT & EdgeHD Adapter V2 for Off-Axis Guider has a longer optical length—38mm. The adapter’s longer length provides DSLR cameras back-focus spacing for Schmidt-Cassegrain and EdgeHD optical tubes in conjunction with the Off-Axis Guider without the need for extra adapters or spacers.
The Large SCT & EdgeHD Adapter V2 for Off-Axis Guider is machined aluminum black anodized. The internal surfaces are sandblasted to help prevent glare and provide the highest contrast. The adapter has a knurled surface providing a great gripping surface for threading and unthreading.
