Hi all,
I've been busy with other things and of course the weather hasn't been that great so it has taken me a while to finish this project.
This is a Ha/RGB blend with the Ha taken through an Antlia dual-band filter and the RGB just unfiltered OSC.
The scope was a MN190 and the camera a ZWO 2600MC. Whilst I also had some OIII it was pretty thin and didn't really add much, if anything, to the final image so I ended up leaving it out.
The final image is 4 hrs of Ha (captured in late June) and 4 hrs of RGB (captured in late July) for a total of 8 hours under Bortle 7 skies.
Higher res version available here:
Astrobin NGC 6559 / IC 4685
Comments/critiques always welcome,
Pete.
