The document looks good to me. I do have a question though...
I am presently running APCC v184.108.40.206. I was reading your description of the "Dec Arc Tracking on a mini Dec-Arc-Model". This is essentially what I have been doing for the last year and a half since I got my Mach2. My APPM parameters are a little different - horizon limits and RA spacing - but I set up three lines with 2 or 3 degree declination spacing. It works so well that I have lost track of where my guide scope and guide camera are stored.
I understand that the new version of APCC Pro has an "Enable Dec Arc Tracking" button somewhere [presumably in the pointing model tab].
My question is... If I upgrade to APCC Pro v1.9, what does the "Enable Dec Arc Tracking" button get me that I don't have now? I read in the release announce by Marj that we get a "Declination-Arc tracking algorithm." and that "This new algorithm is an alternative to the normal all sky tracking model that APCC Pro uses." However, I haven't figured out how the new algorithm improves on what I am doing now.
I'm one of those "if it isn't broke then don't fix it" adherents as far as my imaging software stack is concerned. I have been waiting to upgrade to v1.9 and haven't really felt the need to do so since my current version is performing flawlessly. I will upgrade if there is a performance advantage over what I am using now though.
Thanks in advance for your advice.
