In the spirit of making lemonade from the lemons of poor seeing I whinged about in my last post a month ago, I decided to add RGB to my luminance after all. This is now 16.25 hours of LRGB cropped slightly and reduced to 70% to compensate for seeing induced artefacts.
One thing's certain, while it's quite photogenic, this is tough target - especially when good nights around here are so scarce! Note that the glare at the top right of the full frame is from the yellow 6.7 mag HIP 113240 - just out of frame.
Very nice Marcus! Doesn't quite have that "clarity" that you're looking for but we can only work with the skies we're dealt Not a galaxy I am familiar with but it certainly looks active!
Hi Marcus,
that's a good result on a magnitude 11 target.
Your supreme optics are limited by the seeing.
It's hard to find better unless you go to CHART 32.

Cheers Colin. What I don't have in sharpness I tried to make up for in colour. There's certainly plenty going on in there and I was happy to see the HII regions showing up so well.

You're too kind Allan - a couple of others on IIS have also produced sharper and deeper versions than mine. A few nights of sub 2 arcsec seeing would be nice once in a while!

I've had sub 2 arcsec seeing only once in 5 years in Melbourne
& that was with an Ha filter.
One night it went to 7 arcsec & I had to pack up the telescope.
While it might not be the image you want Marcus, it's still a damn fine NGC7424. And you can always think of it as practice for that special night.
I like it.

Nice final result Marcus...the seeing will come your way... eventually

Cheers Mike ... I hope you're right!

Marcus, I've played around with my 14 hours of luminance. If you don't mind I can just put a link here. Let me know. It's not something I want to leave up on my site....at least not yet. Even after 14 hours/dithered and some smoothing attempt the background is pretty shabby. I did manage some detail though.
