I have been having fun using SGP tonight, after being frustrated for the past week and a half. I still have bugs to figure out before I can do everything within SGP, but I do need some information.
In addition to taking some light frames, I also needed to take bias, flats and darks with my Canon 600D camera.
I did some math, and figured that my Bias needed .00025 second exposure.
I used the histogram to adjust my exposure time for Flats to .15 seconds. From what I have read, the peak in the histogram should be in the middle of the graph.
But I had a problem, and that was that when using BYEOS, my camera is set to the “AV” mode. But SGP did not recognize this setting. I ended up having to set to Manual (B) before SGP was happy. Is this correct, or am I missing something. What is the setting you use for taking Flats with SGP, Manual (B), or like with BYEOS, “AV”?
I guess for tonight’s data, I am hoping the "Manual (N) setting will be ok, especially since I stack everything with Derep Sky Stacker (DSS)
I will try again after I finish my Darks to redo the Flats via “AV” mode, now that I know the exposure time. Hopefully it was an exposure time problem.
