This is 30 subs, 10 darks, flats and bias.
Using PI and following "Harrysastroshed" beginners tutorials. How does this look??

30 subs, but how long? I'd guess that they were fairly short since the bright parts are looking good but you have some way to go in getting the faint detail. Sometimes this is because the black point is clipped in processing but that doesn't seem to be the case here.

Nice result. Your image shows some of the dark dust lanes near the core. Great.

There seems to be slight vignetting in the lower corners. This can be taken care of by using DBE (division) in the linear stage.
