Gentle approach using photoshop & gradient exterminator.

All versions here might be better if you could upload your original TIFF.

But I did? Or what you mean by original, the one without color correction?

Here is the link to the Tiff that is rgb corrected in IRIS but nothing else if you want to have a go at it.

If it is cloudy now and you haven't altered your lens focus you could take flats now. I have a cheat method I use light box on my android tablet and balance it on my camera lens. So far the flats taken that way make a difference so they must be good enough even if not an ideal method.

I have already altered it so can't do this, I know there are ways to create artificial flats and I will prolly try these later.

I wish I'd had such a good first attempt! I can definitely see the nebulosity though it needs some more processing to remove the vignette. Once that background is gone I think it will be much clearer to see. And that's just a total of 10 minutes of integration time. Imagine what you're going to achieve with an hour.

Yea my processing skills are pretty much nonexistant, IRIS did the heavy lifting, I tried DSS first but it couldn't remove the bias/offset properly (it showed as red vertical lines, worse on the right side). If the skies stay cloudy I will try different methods of stacking etc.

If I get clear skies I'll try longer subs 15 to 20 secs and maybe ISO800, and when I can determine the best sub lenght & ISO I'll actually move to a proper dark site and try there. But thanks for all the encouragement  from now on I'll take flat frames also, the lack really shows

I guess this is as good a thread as any to share my first serious imaging attempt

59x10s ISO400 subs stacked in IRIS with median option. I used Bias/Offset frames, can't remember if I ended up using dark frames or not for this. No Flats though and it shows

RGB was corrected in IRIS and the final stretching was done in some old PS I had laying around.
