Simon,
Really love that rendering of ngc6604, nice pastel colours. Unfortunately for me that target is a bit of a sore point at the moment as I'm failing to understand what is going on in the frames I have. In mine if it ever comes to anything ngc6604 will be merely a pimple in a much wider field of view. It's nice to see it more close up, definitely does it more justice.
Regarding ic1841, very unique and interesting, but I'm not convinced that it is actually that target. Couldn't reconcile it to a couple of images I looked up. I believe this is taken at one side of the nebula, I think east, but I get confused at times with orientation. Nonetheless a nice image and something that rarely gets imaged, so nice for that reason as well.
Need a break, don't go posting any more just yet.
Best regards,
Ray
