Hi Jim,
I have an orion steady star and that incorporates pretty much the same off axis guider setup as the deluxe. I initially had some issues on my first night out trying to get it setup using stars. it was a frustrting long night with nothing to show. But what really helped me was a few days later I had a clear night and the moon was up.
Being such a big bright target it was pretty easy to first get the main camera in focus, and then pop an eyepiece into the AOG to see what was going on. It was quite a bit out of focus (and I also spent 5 mins trying to focus a reflection
) but eventually I got the moon into view in the OAG and could tweak it.
I then added spacers so I could get the main camera into focus as well. Then started moving the scope around to work out where the OAG was in relation to the main camera view. Once I had it worked out, I was able to replace the eyepiece and add the spacers needed to get both cameras into focus.
I found this extra easy with the lodestar autoguder camera. because this camera slides into a 1.25 holder, I could add extra long extension to the AOG, bring the main camera into focus and had abou 6 cm of slide to play with with the OAG.
Let me know if you need need any other info.
