Without know what your setup is, here’s what I do see:
The weirdness at the bottom and right of your frame are stacking artifacts. This is caused when the framing shifts between exposures. It’s not unusual but should be cropped out.
It doesn’t look like any calibration frames where used, especially flats. That’s why you image is bright in the center and falls off towards the corners.
There is some tracking error as stars are a bit elongated even in the center of the frame.
My guess is that this was taken with a DSLR and lens on a basic tracking mount?
yh if ur tlaking about the wierd frame stuff along bottom and right side thats a editing mistake but my set up is sony a6000 and a 50mm f1.8 lens but yh its more of a im not sure how you want it to look like to get mainly some tips incase its over edited under edited so on so on i get really good pics but its just editing really i did use deepsky stacker as well to stack 100 photos
Well, you still have stacking artifacts that should be cropped out. It won’t help you with this image but in future your images will be much improved if you use calibration frames (biases, darks and flats).
For flats, point the camera at the clear sky near the zenith just after sunset and take 20 frames exposed to about 50% on the histogram. The aperture and focus should be the same as when taking your subs. This will correct your dark corners. These will be used to even out the brightness of your image.
For darks, take 20 frames with the lens capped just after you finish getting your main images. Use the same exposure time and ISO as you used for your image(s).
For biases, cap the lens and set the exposure time to the fastest possible. Set the ISO to that used for your images and take 20 frames. If you use the same ISO all the time, this set can just be created once and used over and over again.
In Deep Sky Stacker, include all of your calibration frames before stacking. I don’t use DSS so I can’t tell you in detail how to do that but it should be fairly obvious.
One last point. You should be shooting RAW and any in-camera noise reduction should be turned off.
