Pattern in image ASI1600mm Pro

Postby Astrobug » Sat Feb 10, 2018 11:13 am

This is a stack of 20 image of 180 sec on unity gain with a H Alpha filter.
I get some kind of horizontal pattern.
I used APT and PHD2 with randon dithering.
The picture on the left side is mine and on the right side is from someone else with the same septup.
Any suggestions?
I get the same result with and without the calibration frames.

It can be best see in the flats.
Are these all dead pixels?

Hi,

I am having the same issue I amafraid... My ASI1600 MM Pro is practically new, after my first sessions I could never process my images without this strange noise pattern ( I also used unity gain ). Could it be better to use the HDR setting instead ?

Maybe I'm wrong but do we get this patterns only on the early pro version?

Thx Sam for the fast repair of my camera. With the bad weather of this week I could only do some falts and they are now good. I hope to do some real life shoots soon.
