I finally hooked up my SSAG and played with it the other night. I captured a log and can't find anything that tells me what information is in which column. Can anyone point me in the right direction?

Thanks,

I asked the same question last week and was referred to this. I didn't get far, was able to figure out how many arc seconds the star was off from the lock point on each exposure but don't know what that really does for me. The real time graph in PHD is much more useful as you can adjust your settings to get a feel for how it's affecting your guiding real time.

Jeffrey,

There is a free program called ( I believe ) PHD-analyzer
It makes graphs from your log-file!

This is what I have in the readme:

PHD LOG Analyzer V2.03 Changes:

A couple of bugs were fixed but the main changes were made on the PEAS export routines.

Now, you can select between DX/DY, RADistance/DECDistance and RADuration/DECDUration to define the compatible PEAS Log file data.

The PEAS Log will be stored on the same directory as the loaded PHD Log file.

Every PEAS Log will be identified with an extension related to the choices:

DX/DY ---> original log name and "-PEAS-DXY.txt"
RADistance/DECDistance ---> original log name and "-PEAS-DIS.txt"
RADuration/DECDuration ---> original log name and "-PEAS-DUR.txt"

So, you can compare any set of data using PEAS.

Just Google a bit and you'll find it!
Hope that helps you a bit more!

As for the original question:
Frame,Time,dx,dy,Theta,RADuration,RADistance,DECDuration,DECDistance

You can also use PECPrep to analyze your PHD logfiles!

Just my 2 :penny:
