Those are excellent images considering your using a camera originally designed for terrestrial / landscape photography
Well done !!
DSLR’s ( except the latest Canon Astro versions ) were never designed for long exposure Astrophotography , but we still use them as they are great way to get into the hobby , cost effective, easy to use and an excellent real time live view
I used a Canon for 3 years under Bortle 8 City suburban skies with my 6” and 8” Newts , it was a great way to start and excellent learning curve into the hobby
However with DSLR’s quantum efficiency is low ( around 40% ) and the sensor electronics has no cooling so noise is a HUGE problem.
You can dither and capture your calibration frames , lower your ISO and run a small fan attached to the DSLR ( like I did ) but you can never really mitigate the noise which in turn reduces your signal or detail
I struggled on year after year and then bit the bullet and bought a ZWO cooled OSC camera. Absolutely chalk and cheese in regards to image quality detail , and most importantly Noise floor etc…
You don’t need a wiz bang super duper telescope, my scopes are cheap newts , the camera ( and guiding ) is everything in long exposure Astrophotography
I recommend to make the move to Cooled OSC as soon as you can afford it , you will never look back. ZWO and QHY have a great variety of cooled OSC cameras to suit all types of Scopes and FOV etc…
Some folk move straight to Mono and filters from their humble beginnings using a DSLR which is my next move in 2023 after using the cooled OSC for nearly 3 years now . I will always keep and use the cooled OSC even when progressing to Mono
