pics

Went out to a darksite and tried snapping some milky way pics with my DSLR while the main telescope rig was doing its thing. Pretty pleased with how this turned out since I don't really do widefield imaging, and it's only 5 minutes of total exposure time (yes I know the stars are trailed 15" exposures were too long in hindsight). The milky way core is home to many different deep sky objects, including all of these that I've shot before, and a bunch more that I haven't photographed yet. Captured on July 18th, 2023 from the Deerlick Astronomy Village (bortle 3 zone)
