The comet Neowise was my first foray into astrophotography. Each final image is a stacked image using 50 individual images and stacking software to reduce the digital noise from high ISO and long exposures. Not long ago you had to purchase a motorized tracker which is still a great way to go but with stacking, you can get pretty amazing results! I set up both of my cameras each with a different focal length lens to capture each image.
