The last of my three targets from the other night was totally impromptu--I just went through the ASIAIR app to look for anything that would be high enough not to be blocked by my house, and far enough from the moon to not be outshone. The one I chose was an open cluster called "Trumpler 24", and since it was going to be shot in the middle of the night (while I was asleep) I only found out what I had shot when I reviewed the images in the morning--it turned out that the main subject appeared to be IC4628, the Prawn Nebula, with the cluster appearing rather inconspicuous below it. Unfortunately, since I was shooting with a one-shot colour camera (the ASI533MC-Pro) I was not able to capture the narrowband spectra that the nebula is so rich in, so instead it has the very red appearance that is more typical of a prawn.
