Hello folks :? ,
Since the bad weather over the last few weeks, I was finally able to do some test with my new ASI183MM pro. I've bought it last October, in order to use it for both lunar and deep sky imaging, after using with success its "little brother" ASI178MM over the last 2 years.
The problem seems to look at the same as :
The noise pattern at 100% size:

You can find here 2 full images with RED & Green filter, along with log files from Firecapture:
-different Red filters : Astronomik type 2c and Baader,
-on 3 different nights,
-different images stacked : 150, 300, 500,
-different capture softwares : Firecapture V2.6 32 bits, Firecapture V2.6 64 bits + Sharpcarp,
-different values in autostakkert : AP size, noise robust, min bright,
-different softwares for post processing : Registax (Wavelet) , ASTRA (Wavelet sharpen), Photoshop (Unsharp mask),
-different gain settings & time exposure : 75, 130, 180, 230 and 2ms, 5ms, 8ms, 10ms,
-different Usbtraffic values : 80, 90, 100,
-3 different USB cables,
-different value of Gamma : OFF, 50, 41, 31,
-with & without the power Supply (but cooling was of course OFF),
As I'm using RED filter for lunar imaging 90% of the time due to bad to medium seeing in my area, not being able to use the ReD filter is like I can't do lunar imaging anymore which was why I've bought this camera in the first place :( .
Please, I need your help to solve this, I was so happy with my ASI178MM and achieved to do some MEGA mosaics of the moon like below and I'm stucked right now with this camera that I cannot use for my purpose :
Thanks in advance for your answer and have a nice day
