EOS M50 Mark II Horizontal Lines on Astrophotos

Hello, my camera is the EOS M50 Mark II, purchased in October of 2022. Have loved the camera for taking night photos, but then the photos started turning up with these horizontal blue/purple/red lines. The picture (ignore that it's crooked) was taken with the 15-45 kit lens, but I encounter this with my 55-200 lens as well.  I've tried all aperatures, all shutter speeds, low ISO, auto ISO, and am frustrated with the outcomes. What am I missing? Thank you for any info!IMG_4487.jpg

What is exposure settings of the sample photo?  The image looks a little noisy.

You could be seeing interference from the artificial lighting.  Do these artifacts still appear when there is no potential for interference from artificial lighting?

Sorry, forgot that part.  Lens was at 15mm so wide open, with f/5.6, 30 seconds, ISO 100

Greetings,

Do you have other recording media you can test with also?  Does this happen to some extent when you take shots during the day?

The daytime shots are fine, it is the night sky shots that come up with the lines.

Do you have a raw file to share?

Lines like this have been found in R, 5D IV, M5, 80D, M50, 1D X II when under exposed and pushed in post.

I do wonder if it's my photo editor doing this - which is level one Microsoft photo. When trying to upload the raw, this Canon forum page will not allow it, so that is why it is in jpg form for now

Use a file host.
