Used 85mm 1.8 lens and stacked 322~ images in DSS. Any critics and suggestions are welcomed

Tracking looks okay, just need more magnification i think to get detail. This is just my opinion, know how hard it is and i commend you efforts.

Thank you. I haven't used any star tracker. All the images are 5' exposure ones, stacked in post

So you are not offsetting planet rotation, if not that could be why the detail is not there. Images look well aligned for it.

Is there any tutorial for that?? I'd like to learn about it. I have treated this similar to any other galaxy and went on to stack them

Its a deep rabbit hole and i dont know your gear. I assume your manually plate solving using known markers and using just a dslr and lens? Maybe look at skywatcher az gti. Eq mounts, polar alignment, star alignment and away you go. Plenty of videos on youtube, have fun and clear skies.
