NGC 281 Pacman Nebula.
I have a Zwo ASI071MC Pro camera and with it, narrowband in Ha and OIII can be rather easily captured with dualband filters, in this case the Optolong L-eXtreme. Capturing SII is another story though: it's possible but since only the red channel has real useable data in it, you have to capture more/longer in comparison to a mono camera. This of course is not stopping me
First image is in SHO Hubble Palette. It's my second real go at this, so I'm pleased with the result
But I always "play" with the data I have and in this topic by Tim, there were some cool examples of that plus an URL to a site with all kind of combinations.
I took that a step further and came to a OHS version on which I applied the same methode of getting a Hubble Palette.
This gave the second image where the SII shows very clearly as Blue and OIII =orange/yellow and Ha = green/blue. I rather like the effect

Hi Menno,
I'd say that worked pretty well. 3h is not a massively long time - I am guessing that the reducer probably helped a bit?

Hi Tim
Yes, the reducer helps indeed. And no, 3 hours is not a lot but with a mono camera it would have been (a lot) better in this case
