Had a go at the orion nebula yesterday. First outing in a long time, just 30 x 5min exposures, with some Ha. Here is the first stab:
After a day or two, I decided to look again, and see what we can pull out of the data. Two and a half hours of capture roughly equates to about 1 Gigabyte, so there is a lot that can be done. Here is the final that I will settle with on this acquisition:
So last night, we obtained some more Oiii sub-exposures in order to bring the number to the same level as our Hydrogen Alpha sub-exposures. I also started to obtain some Sii exposures, only managed 10 or so for each pane of the mosaic.
It looks like I should obtain more Hydrogen Alpha sub exposures as well now, as the quality does not appear to be as good as the other narrow-band wavelengths, and of course Hydrogen Alpha is a strong part of the composition.
You will notice we are now using a different palette for the RGB composition.
I probably need to flex up some of my GIMP processing skills as I still feel I am floundering around not really knowing what I am doing.
Anyway, without further ado, please find below the current rendition:
