Nice image.
I use only 5min subs actually, to avoid differential flexure (yeah I know, I should do something about it..I will, I will...). checking the peak of the histogram curve, ADU background on a single 5min sub is about 2500, on a 90 min stack of 5min subs about 500...?

The title says it all and from your fantastic image it's pretty obvious we are!! I can just imagine it now, the hills of Wallaroo would definitely come alive with this blasting across the countryside...

Yes, agree about the title...but sorry, Pav rules

Thanks Marcus, yes it is fields such as this that I really wanted to use this scope for, there was no chance under the blurry and heavily light polluted skies of Newcastle hence the monopoly on colourful emission nebulae with NB filters for over a year.

Not that much really, there is some foreground galactic cirrus in there but although there was little wind and average seeing, the Lum was taken on a night of poor transparency and some high cloud and the RGB with a near full moob, so I couldn't do a good job of revealing the galactic cirrus. It's there but has been corrupted by gradient removal anmd high cloud, so I am not sure what is GC and what is redistributed background and or Earth cloud so I didn't try and enhance it.

Note: your link to NGC 5054,
the image has a typo - it says NGC 5044.

This was the only other image I could find of NGC 5054:

Cheers Allan, not an often imaged galaxy area actually and I have fixed that typo, thanks
