Atik 383 glow

Attached is a Ha sub of 20 minutes.
What is causing the light at the top of the sub ?.
My OII subs do not have this.
Regards,
Simon

Hello,

Are you subtracting bias or dark's from your images?  Are these the same for both the O2 and HA?
Best

This is a 20 min sub no subtraction.
The OIII 20 min sub is perfect.
