The Celestron Large SCT/EdgeHD Adapter was made especially for our Off-Axis Guider (#93648, sold separately). When paired, these two imaging accessories allow you to use the full image circle created by a 9.25”, 11” or 14” SCT or EdgeHD telescope.
The Off-Axis Guider is an essential astroimaging accessory for long focal length telescopes that require the most accurate guiding possible. The Celestron Off-Axis Guider uses a prism to intercept a small portion of the telescope’s focal plane (outside the field of view of the main imaging camera) to locate a guide star.
