Question Re AO
As I consider whether to venture into long FL astrophotography with an f10 12" I think I might need to consider AO as well as OAG or ONAG guiding. I understand what this does and how it works, but from a practical point of view am confused. I get that you need a fairly bright star to the guide camera which is running at a high rate, and this provides info back to the AO to make corrections to the light path. But then, how does the mount receive correction? Does the same AO unit provide output to the mount, or do you need a second guide camera driving normal guiding software to provide periodic mount corrections? I did read on the SBIG site a statement that AO can replace mount guiding entirely....is that what is normally happening or how those of you with AO are using it?
Also, is it possible to run an SBIG AO8 with the ST-i camera?
Thanks!
