Cheers everyone
Wasn't overly happy with this really, couldn't work with the data too well. I had rotated the camera since the previous imaging session a year ago and in the meantime I had a lap top repair earlier this year including a new hard drive, so the original files weren't in the laptop when I started out at the observatory, so I didn't have a reference frame to match up with...sooo I just guessed the framing based on memory. Needless to say my guess was off by a bit and this resulted in serious cropping being necessary, hence the bubble at the bottom left being cut in half
.... but meah, an image is an image
Andy, if you map SII to Red, Ha to green and OIII to Blue...this is what ya get, one must heavily tweek and remix it to change it to something else (which
is fine to do BTW). The Red SII was just in the edges of the nebulosity, hence it is mustard in those bits, the OIII is confined mostly to the big bright patches, hence they are quite Blue and of course Ha is very dominant so plenty of green mixed in the rest of the image. This resulted in what I think is still a mix of more than just green and blue as there
are turquoise and mustard hues in places too...but yes green and blue are the dominant colours/hues ....that's just da Physics I guess?
I might do an Ha RGB version yet too
Mike and Trish, yeah I remember yours, t'was a good'un despite your Learner plates
I remembered that faint bubble in your shot too but as I said above, errors in my reframing over the space of a year meant it got cut off

It's good to see an unusual subject as the main attraction and I like the offbeat colouring as well.
not much structure in
