Hi

A few things to look into are

1) Why so little signal for 5 hrs work , this is urgent

2) more work on gradient removal

3) look at your colour correction and saturation ( weak )

4) noise reduction

What program did you use to stack this image , what does one sub look like ?

right first what would cause to have so little signal would living in a city with lots of light pol be the problem ,im in the process of taking some bias and flats as we speak just had a go at colour correction i used dss below a single stack

There are a few more "tricks" to using Gradx..

Did you check ou the tutorial in the link I sent you about how you use it in "stages" ?

Also if there is uneven illumination around the edge of the stacked image it's worth cropping this out before you use GradX...

Certainly getting there though

hear we go green no more

[omneferuss]

Even better !!

...if it were me, I'd now try the tiniest tinest hint more of blue and a weeny bit of extra contrast.. then possibly, after that I'd probably see I wanted the feintest whisper of red.. hehehe

but where (and when?) would it end ?!

As your 'data' gets better you'll be turnin' out some crackin' stuff !!

[astrokat]

soon as ive finished work il give it a go, where do i find contrast in ps

thanks for your help
