Nice !!
When you start guiding you won’t need the volume of exposures to expose detail as your subs will be longer and produce a lot more detail
Also one noticeable thing will be the shape , sharpness and density of your stars , you will see more diffraction spikes on the dimmer stars as well
I looked at some of my unguided images 3 years ago and couldn’t believe how out of focus I was when zoomed in close plus stars were oval or eggy ( at the time I thought they were great )
