Oh, big mistake from me!: I mean the "Remove  Amp-Glow", NOT Light Pollution !! Big Sorry to all !! 🙂 But the statement and question still applies.

@wacky So, Remove Amp Glow is an option in Tab 2 and that has not changed as far as I know. How old are your darks? Did you process your lights with these darks in an older version of APP and did you see that it indeed works there?

Hi Wouter! 

I'm pretty sure that the Amp Glow Reducing worked without darks in the beginning. But I also like to admit if I've done something wrong .. The last Darks are new, but were recorded shortly after the camera was switched on. Is it possible that the amp glow on the ASI 178 cameras only comes after a certain operating time?
I will try it out, first of all thank you very much for the quick answer! .. 🙂
I haven't been "in APP" very long, but I'm already a passionate fan! :-)) And the extremely good automatic functions "prevent" from reading deeper into the matter ... 🙂

Dear Wilfried @wacky,

The Adaptive Pedestail/ reduce Amp-Glow function in 2) Calibrate, will only work/be applied when darks/MasterDark(s) are used to calibrate your lights. So it never worked without darks.

If you create darks for a camera like the ASI178,  you need to make sure that the darks match the light frames for

• exposure time
• sensor gain
• sensor offset
• sensor temperature

If any of these do not match the characteristics of the lights, then amp-glow probably will not be removed completely. This is because Amp-Glow is a non-linear signal. You can only calibrate it out perfectly if the darks properly match the light frames 😉

Since the Amp-Glow is non-linear, you will see indeed, that for example a 60 second exposure will show very little Amp-Glow and a 120second exposure would all of sudden show more than 2x the amount of Amp-Glow, perhaps 4x as much. That means that it works non-linearly.

Thank you, Mabula. Then I had the "wrong thing on the screen", apparently I used Darks before. You never stop learning; but that's nice too 🙂

It's my life's motto! I love learning. Work though... 😉
