The AO-8 is a second generation adaptive optics system from SBIG specifically designed to enable an SBIG camera user to obtain the ultimate in image resolution that his/her telescope and site can achieve. The AO-8 is a replacement for the former AO-7 and can only be used with ST-7/8/9/10/2000 USB cameras.

The current AO-7 Adaptive Optics accessory was designed for the smaller CCDs in the ST-7/8/9/10/2000 cameras. It is not recommended for use with the larger format STL series cameras. A larger moving element is required to eliminate vignetting of the larger CCDs and also to maintain good image quality due to corrections over the entier field of view.
