This full frame SCT / EdgeHD adapter has been designed specifically for Celestron's Deluxe Off-Axis Guider.
You can utilize the entire image circle of 9.25 ", 11" or 14" SC or EdgeHD telescope with this off-axis guider and adapter. This combination is especially interesting for users of full-format cameras such as the Canon 5D Mark III or 6D as their larger sensor is better illuminated by the larger SCT and EdgeHD telescopes.
The adapter is attached directly to the SC or EdgeHD telescope OTA.
