This has been giving me lots of grief - my pictures turned up too blue. (3.5 times as much blue as normal) - i foudn that using my MasterBias file (from my library) made it so the final image was 100x more blue than any other colour and made it unprocessable.

I stopped using the master bias and i managed to get this picture.

I am going to do this processing again when i have taken a new set of calibration frames

Description: I did this picture by forgoing darks as part of flat or light calibration as they totally messed things up.
I think i have found out what my technical problem with the ASI294MC was though and why it was recording too much blue. I had changed windows user account and i did not re-install the ASI drivers - APT still worked which is why i did not think anything of it. I have re-installed the drivers and i created a few darks during the day which seemed to have decent colour balance (although with lots of light leaks as i can't take darks during the day no matter how much i cover up scope)
Tonight is a the big test though and i will be seeing if camera behaves itself. Things will be slightly impaired by the moon - but not enough to see if the camera is working ok.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
