I am relatively new to SGP and PHD2. I have done a lot of reading, searching and youtubing to get to the bottom of this, and I think it is a calibration problem. When running a sequence, I am getting a long wait time after each image, even when not dithering. Last night it took over 20 minutes to capture three 90 second images. Most of the time I was waiting for SGP to settle. My guiding RMS was between .30 and .40 at the time. I was imaging the Wizard nebula, near the meridian. Seeing conditions were ok, with a full moon and occasional light clouds, but I never lost guiding. I had the auto guide settings in SGP set to High Dither, every 5 frames, Settle at 0.3 pixels for 5 seconds. I am using a 190mm guidescope and an ASI 120mm mini cam. My mount is a Losmandy GM811G and my scope is an Explore Scientific ED102CF. I am pretty sure that I need to change the Settle at to a larger pixel size, but not sure how high to go. I have read quite a few forum posts on the subject, but do not understand a lot of it. I don't want to just keep plugging numbers in and see what happens, as we don't have very many clear nights and winter is coming.
I have the latest version of PHD2 and SGP is at 320613
Thanks for reading.
