Hello guys this is my 1hours and 22min stack of Pleiades and its surrounding nebulosity.
Telescope: cheap 114/500 newt
Mount: EQ3 pro
Cam: Canon R50
Subs: 2 min - ISO 3200
Filter: SVbony CLS
Bias and flats both 40 frames.
Walking noise is better after advice from @glad widget Thanks a lot

glad to see dithering worked, have you done any kind of background extraction?

Hmm, for almost an hour and a half I feel like you should be seeing more nebulosity.

Odd, I live in a bortle 8 and was able to see some nebulosity in my eight minute exposure. Your scope seems to be collimated, maybe dew or fog on your mirror, or something wrong with the camera?
(granted it's not a lot but somehow it's more than this)

yeah, if your mirror is cold and the air is warm (or vice versa), moisture can condensate on the mirror, and the image quality will be reduced quite significantly

idk whats wrong maybe i would try to shoot subs with ISO below 800
maybe there is more noise than nebulosity
but I need to upgrade my setup a lot new telescope smthing like sw 150pds heq5 and mono camera

Lowering the iso and taking more subs would be a good starting point

I watched some graphs about readout noise seems very high at ISO 3200
