Green Images

Post by EDGCOMBE » Sat Aug 11, 2018 1:18 am

I have a ASI294 MC Pro only two months old.
I use Nebulosity to capture and processing.
I had no issues for a few weeks then after debayer the images were green. On processing the image run most were normal but then for no reason “green” which is unable to be processed out.
I checked everything I could think of and all the forums. I posted the image on the ZWO Facebook page for suggestions.
I reinstalled Nebulosity just incase, swapped the USB cable as I have another ZWO camera, used a different laptop during capture. I put it down to a one off.
However tonight same issue fine for the first hour then in the middle of of a session green and every imagine after unfortunately you can’t tell until processing. It’s not the debayer setting as fine for the previous images. Not Nebulosity as I also use with my 224 and no issues.
I thought it might have been the nearly full moon rising and moon glow the first time but last night was a new moon.
I also checked and the cooler, fan and temperatures read out were a consistent -20. Just incase a cooling issue.
I just notice when going through the processed images before is goes green the file size is 42.5MB then when it goes green in the middle of the run (nothing touched no changes) the file size decrease to 360KB on the green images post processing on the original capture it’s also short of data from 17.3MB to 17MB.
Any suggestions welcome thank you. :D

this is because green is the most sensitive color of ASI294
you just need to do one white balance in post-processing

I cannot understand what do you mean cannot process it out

I have tried white balance, colour balance and changing the debayer matrix and still green is as if the only colour is green. Why does the file size drop and would it start in the middle of a run for no reason? Then i try the following night change nothing a normal images.

19.5 seconds later in the same run then continued green for the rest of the night. No cloud clear skies.
Previous un affected images processed no issues. Affected images unable to make any colour than green.

I have downloaded ASICAP what info do you need?

I don’t think it’s software as my 224 works perfect on Nebulosity and I even tried a older version on Nebulosity for processing.

I have up loaded raw images above.
Thanks
