Well you certainly chose the worst conditions to introduce yourself to astrophotography but you've pulled off a very successful set of images. Great job in taming the Light Pollution and moonlight with clever consideration to lots of short high iso exposures to accomplish this. Well done! You will obviously improve your outcome without the moon, not much you can do about the Bortle 8 skies unless you change your location. Also, investing in a Coma Corrector will eliminate the elongated stars at the edges. You have a T-Ring to connect your camera to the telescope, I assume? The CC will screw into this and then slide into the 2 inch eyepiece holder. Good luck!
