This is my first attempt at using autoguiding to take longer exposures with my freshly astro-modded DSLR camera. I feel the moon phase (70%) and light pollution filter may have hindered my efforts. Try try again. Thank you to all of the talented and experienced astrophotographers out there for the inspiration to keep learning more about this fascinating hobby!
