Here's one I've had to wait several years to be able to image, first it was the fires, then it was the rain, then it was work. But I've managed to squeeze in some early morning imaging time and finally got several hours on this magnificant nebula, After seeing what i've got so far, this is one that I'm going to be coming back to again, I really want more depth in this.
I was very surprised to see the second tiny planetary nebula right at the bottom of the Dolphin, after a bit of searching, I did find that it has a designation -
PN G234.9-09.7, but no "name." So I think I'm free to give it one?
This is just under 9 hours total, ~5hrs OIII, ~3hrs Ha, and 15m each of RGB.

The processing was a fairly standard work flow for my HOO images.
Stars:
LinearFit > Channel Combination > SPCC > StarX > GHS to stretch
NB:
LinearFit > BlurX > StarX > NoiseX > GHS > PixelMath to combine into HOO > CurvesTransformation for colour adjustment
PixelMath to bring the stars back, then BlurX for slight star reduction.
Clear Skies, and thanks for looking!
