SBIG AO-L Adaptive Optics for Large Format STL Cameras
Your card will only be charged once item ships.
The AO-L is designed for the larger CCDs used in the Research Series cameras, however it will also work on the ST-7/8/9/10/2000 cameras. The AO-L uses a transmissive correcting element instead of a reflecting element. The full scale correction rate is slower than the AO-7 at about 5 - 10 Hz, but individual moves are actually made quicker.
