AO-8, for Alen N
The AO-8 when used with CCD OPs uses the guide chip in the SBIG camera.
SBIG advise that other systems (iepossibly maxim or other) may also use the imaging
chip, I have maxim but have not checked thi as CCD OPs is I find the best for
SBIG cameras.. It would appear however that the AO-8 is onlt really of use for
systems of 2m or over focal length, and best when seeing is good. Very bright
stars can cause it to "judder" so must be avoided. - Gerald.
