" Or, if you are in a mobile setup, just model a few declination arcs around the target that you are imaging. It won't take very long to create the arcs."

I know that it won't take very long, but it does mean that I have to be there right at the start of the session. I go to a lot of star parties and am often helping others out with their setups. I usually set up my automation in the afternoon and then let it start up unattended while I am working with other folks. And even when I'm not helping out others, early evening is prime time with my family.

Without the ability to have completely reliable unguided imaging, I'll probably continue to go ahead and guide, since that's nearly bulletproof.

As for a permanent setup, I'm fine with doing a big, high density run once in a while. I just need to figure out what's required in order to have confidence that I'll get good data unguided. I'm not there yet, but will be playing with it for a while.

On the subject of automation, does APPM have any kind of an API that
would make it possible to invoke it from a script with the sample
points for the target? Alternately, is the definition of the PNT file format defined so that I could write my own routine to solve a bunch of points on the declination arc?
If you have a permanent setup you would just model the entire sky as you always have. The only change would be that you might want to increase the slider in APPM that controls the number of points in RA so that each arc has more points. APCC will interpolate between declination arcs.

Or, if you are in a mobile setup, just model a few declination arcs around the target that you are imaging. It won't take very long to create the arcs.

Great. I'm looking forward to it.

Hi Wade,

Can I do dec-arc modeling with the current APPM version? Is it as
simple as making a model with just a bunch of points on my target's
declination? Or do I need to wait for the next CP4 firmware and accompanying APCC release to use it?
The Dec-Arc modeling feature has been well tested for over a year and
a half. As mentioned previously, it will be in APCC Pro version 1.9, which will be available soon.

The Dec-Arc modeling does not require a change to the way APPM
operates. By default APPM can collect data points along declination
arc paths. It is APCC Pro that implements the Dec-Arc tracking feature, which can be turned on and off at run-time with a single checkbox.
