I've a doubt.

Astrophotography at 3200 my files show already lots of noise in a EOS R.. os it normal?

Each panel of the mosaic is a stack of 8 exposures and this stacking gets rid of the noise.

EOS R is not particularly noisy at ISO3200 but a Sony A7riii is a bit cleaner but it gets noise artifacts in the shadow areas that consists of red/blue speckles. The EOS R does not get that.

Also the star colours from the EOS R are very good and natural whereas the Sony tends to artificially create some greenish stars due to the RAW filtering Sony does.
