How I Captured a Comet With a Fast Telescope and Short Exposures (Comet Panstarrs C|2017 T2 )

Comet PanSTARRS (C/2017 T2) was a bit far away to see a lot of movement, but I still managed to capture something over a 40 minute duration. With the moon at 84% illumination and lots of haze, I used a Celestron RASA and very short exposures of 15 seconds to capture the comet.
