Fox Fur and cone
The demise of a rather large Gum tree on my neighbours property has opened up my northern sky quite a bit.
Sitting well within some serious light pollution from Sydney (to my North), this rather dim nebula proved to be challenging.
Much more data needed...but hey, there is only so much you can do in one evening....and of course the weather has changed to rain and cloud...so I'll call it a work in progress
Anyway, here is the link

That looks amazing Peter, really nice details.
did you have LP gradients in the RGB subs, how do you process it out?
since you've used Ha for L, that would've been straightforward, but RGB usually gets affected by LP.
Cheers

As I live in light pollution central, gradients are something I simply have to deal with constantly. The RGB data was indeed all over the place, but nothing more exposure won't fix...assuming the weather clears...as I'd like to bring out some subtle colour details which are only hinted at in this rendition.

A remarkable image. It has a kind of transparency and clearness to it you don't often see.
You must be delighted with this world class setup.

Ta Greg. I should post a DSLR image of my northern horizon....in fact when the weather clears... I will. I think many would not believe how tragic my skies are.
But the system is now tuned and working really well. With the AO-X guiding at 5Hz my narrowband FWHM's are around 1.6 arc sec.
I'd love to have a dark sky rig.....maybe one day

Very beautiful image there Peter, and it's such a stunning nebula. A top result for sure, nice! 
What's your visual limiting magnitude btw?

Thanks for the feedback Rolf.... The limiting magnitude in that part of my sky is probably 3-ish... this fisheye view was taken a few years ago
Fortunately my neighbour doesn't often use his mini-sun outdoor floodlamp much these days...  ...I guess his power-bill was getting out of hand

That made me laugh - a mini sun floodlamp! I am sure we have all had the pleasure of that experience when imaging!

Might need more data but what you have seems more than adequate to me. Nice one Peter.

Nice Pete. I am thinking that a RH is going to replace the mighty TSA for imaging wide field. I am looking at the OS version but will not be getting a huge camera and putting it on the scope. Maybe an STXL6303 or STXL11002. This image shows the type of field width I can expect. I am going to say you would maybe on need another 4 hours or so in Ha and maybe even another hour in each colour for it to really smooth out. The TSA would be 40 hours.

This image makes me hate you.
It also makes me want to shoot that area.

Excellent result Peter!
I find it amazing how smooth your image is considering the (relatively) short total exposure time.
What is your sampling with this setup?
cheers

A lovely image Peter! Especially impressive given only 105 minutes of exposure!  I'll even overlook the fact that it's not full res ... just this once though  .
Not sure your getting a lot of value from an AO-X at 1160mm (??). I only ever needed to use my AO-L at F11.7 on my Tak.
Cheers, Marcus
PS: And thank you for not giving us another B&W standard candle.
