Thanks to APP Beta 2 , my wife was able to get her target of IFN or flux near Iris Nebula. No matter how hard we tried , she could not get the subs to behave in PIX. so we tried APP beta2 and LP remover and Voila , saved .

here is the specs : 

ES20839 Newt , ZWO 294MC, CGX, 

750 x (60 and 90) sec mix. ( Unity) SQM 20.20 / Bortle 4.5.

everything done in APP.

here is the 2 results for both software. one is DBE/ABE the other is "remove light pollution" in APP 1.083 B2

Go3 St1
fullSh2 session 1

pushing it hard below.. 

SH2 mini

you can plainly see the difference... Thank Mabula.

Pff, amazing, I guess you can get it with pix as well but it's clear app does make the process easier. Thanks for sharing!

@rcfmitch Really well done! Still, I wonder where the central circle in the first picture comes from. My suspicion is the flats so perhaps with the right flats you can eliminate that and reveal even more IFN?

@wvreeven Agreed .... after making 200 flats @ ADU 5K,10K,15K,25K,20K,30K,  ( 1.5 sec 3.0 sec exposures) NOTTA... lol

it might have to do with light leakage on the 8 inch F3.9 / ZWO 294MC.

yet they were done at night with EL panel.   never happened with the ZWO533MC,  AA183MC IMX TEC.

strange.

@rcfmitch

I have the same camera (294MC) and had some issues similar to that first image when I first started taking flats. 

I use APT for capture and the Auto Flats Aid just didn't like the camera. With an ADU of 25,000 the flats looked fine but over-compensated when being calibrated with the lights. 

The solution for me was to use the timing figure given by the Auto Flats Aid but just shoot Flats manually as you would Light frames. Same for Dark Flats and the problem was instantly solved.

I don't know what you're using for capture but it might help. Flats are an issue for lots of people with the 294MC.

This is why I always use APP. There is a way to get DBE to deal with that particular scenario but it requires use of the geometric functions in DBE. Search for Adam Blocks tutorial on geometry for DBE. But, with APP there is no need and I still cannot find a processing suite that is better and easier to use for background neutralisation and gradient removal.

 

Nice result
