EOS R3 Green cast in edges of the frame in low light

[davidgs]

hello every one,

I have an EOS R3 mirrorless camera, with the 15-35 RF 2.8 and 28-70 RF 2.0, I take pictures of the night sky, it is a low light environment so I set the parameter accordingly, (F2.8, 15 sec, iso6400), when I acquired the camera the recommendation of canon was not to use the profile of the lens, I did make the change and it corrected in 50%.. I replied with that information but I didn't receive more data. couple weeks ago I went to Goblin Valley UT to picture the Milky Way there this is one of the 21 frames I took for a panoramic stich...the green edges and the low resolution in the bottom

White Balance could be an issue so a RAW file would an excellent sample.  When and if you do post a RAW file, try to also post a more conventional photo taken during the daylight hours on a sunny day.

I hope some of this might help. I use hugin on Linux for stitching, so it might be different for you.

Are they raw files? Have you tried changing the white balance in the Canon DPP software and exporting 16 bit tiff files for stitching?

[davidgs]

Every single frame I took (21 frames) for stitching looks like this one.  In raw or JPEG.

I read the cr3 file with DXO PureRaw file as well as Lightroom for catalogin

Any raw files?

I'm in agreement about a white balance and possibly a unintended picture styles modification.

+1, @davidgs, how about some RAW photos for us to digest. please.

[davidgs]

The issue just happens sin low light, the pictures in daylight are just fine, I normally setup the WB to 3800-4000 range. 
I tried couple shots usin AWB and it has a similar result but the rest of the picture is brownish, as you can expected, 

I’ll upload a CR3 file later on

[davidgs]

Yes I will upload a file later today
