Seen some requests to look at some info on the CGEM, so I enabled the guide log in PHD the other night and saved it as a PHD Log and some additional PEAS output that can be looked at in PECPrep. I have attached the PHD file and some PEAS output for everyone to have a look at.
Used PHD Version 1.10.0; I guided for close to 3 hours (the log is for about an hour and a half) using with standard out of the box settings (100% Agressiveness, 10% Hystersis, Dec Guide Mode set to Auto and Dec Algorithm set to Resist Switching).
I opened up the PHD Log using PHD Analyzer (you need Version 3 which can be had at the Stark Labs Yahoo Group under Files/Supplemental Files folders).....checked it out, and have no idea what it means. I guided from my back porch, which is wood framed and is slightly affected by
cars going by or by myself walking away from the mount once everything is set...you can see those anomolies at the beginning and close to the end of the graphs...otherwise I have no idea what any of this info means...maybe someone
could clarify this information for us?
I was imagining using an AT90EDT (great scope) and SXVF H9C; Guidescope was a 50mm Miniborg of 250mm focal length and an Orion Starshoot Autoguider which has 5.2 micron square pixels. On this imaging run, I was taking 150second lights and stars came out nice and round (90%).
I have not fussed with PEC much as guiding has always seemed to mask things, but was kind of interested in what my new CGEM does. My CGEM is sure accurate in it's pointing and tracking...and, used the AllStar Polar Align routine which seems to work well.
