AO for Alex
Hi Alex
My imaging camera is an ST8 and I was going to get it upgraded so that I could buy the AO8. However, I went for the SX AO for a number of reasons.
Firstly, it's completely independent of the imaging camera. This means you can use any camera with it - even DSLRs.
Secondly, the you want a really sensitive guide camera. The shorter exposures that the unit can use the better. Assuming reasonable conditions with the SX lodestar I can always guide on a star at 0.1 sec exposures. This means that the AO makes changes to the optical path between 7 and 9 times a second.
Doing it this way means that you also have a fully independent guide camera for any other situations that you might choose. For instance, you can use it for normal guiding in the OAG if you want.
I'll get a picture of it set up for you.
The general connections are: The AO unit connects to the guide port in your mount and also to the PC with a serial connector.
The Lodestar only has one connection when used in conjunction with the AO - it connects to the USB in your PC.
Your imaging camera connects to your PC in the normal way. It doesn't have any connections to AO/Lodestar/mount.
Hope that helps
Steve
