SBIG - Adaptive Optics accessory for STL (also compatible with dual CCD models ST-7/8/9/10/2000)
The smaller AO-7 Adaptive Optics accessory was designed for the 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
tocorrections over the entier field of view. The 50mm diagonal mirror of the smaller AO-7 would be
placed too far away from the CCD in the large format designs to be effective over the entire field of
view. For these reasons, a new larger AO device has been developed for the STL series cameras. This
new AO is placed in line and has a refractive element that can be made to respond more quickly than the
moving mirror of the AO-7. It is larger, however, and the new AO will not make as many moves per
second as the AO-7, it will however, respond faster when making a move.
This AO is operated via the I2C port on the STL camera, and it may be operated with other I2C
accessories such as the new STL 8 position 2" filter wheel. It is also compatible with any
ST-7/8/9/10/2000 camera having an I2C port. This product is currently in production.
Atmospheric Refraction Compensation: In addition to motion compensation, we are working on an
optional set of prisms that will fit the new AO-L to compensate for atmospheric refraction. We will
post more about this as the product develops.
