Did a sequence last night that contained three targets with multiple frames per target. Dither set to extreme, latest build of PhD2.
What I noticed is that there was no dither shown either in SGP or PhD between frame one and frame two on the first target of the night. A blink also confirms no dither happened. It was set to dither every frame and extreme dither. All other frames showed a dither in both PhD and SGP and blink confirmed they did happen. This was even true of all frames (even the first) for the second and third targets of the night.
The bottom line is that SGP was not dithering after the first frame of the night but did for all other frames.
Anyone else seeing this? If you could have a look at some of your frames and let us know it would be helpful.
FYI, every other aspect of the imaging session was totally perfect!
I suppose that one could insert a very short "to be thrown away" exposure to start the night but that seems like a waste.
