EOS R5 Mark II Astro photos - not coming out well

[Samtata2024]

Hi everyone,

I have been trying to take some astrophotography. I have a R5 Mark II - my settings for these pictures are Manual focus, 15 - 35 mm f2.8 lens.

the picture settings I had at 15 - 20 sec shutter speed, ISO 3200, and f 2.8. I thought 3200 is a good ISo but im still seeing so much pixelation and blur.

The pattern seems to be from the lens correction.
