why does this image suck?

[eternal oyster]

3h integration and I did everything right, why does it have so much noise and artifacts and so little signal?

[stuck umbra]

even if you do everything right, if you shoot in light pollution gradients will get through. As for the artefacts that seems to be walking noise that you can rid of with dithering

[eternal oyster]

Any dslr filters that could help with the light pollution? I'm working on guiding and dithering

[quasi grove]

calibration frames?

[grand ivy]

did you use calibration frames? yeah for light pollution you can use optilongs filters but however they are known for their halos on stars. Antlia's filters should be better at that

however this looks like stray light and light pollution

[eternal oyster]

I did take calibration frames but it doesn't help with walking noise and light pollution

Also how does it work with just a dslr and lens?

[grand ivy]

filters? for telescopes you can get one to screw right in between, for lenses I believe you can get clip-in filters

it like goes on top of the sensor like this:
