How to Photograph the Elusive Polaris Flare

This video shows every step of photographing the Integrated Flux Nebula (IFN) around our North Star called the Polaris Flare. I show how to accomplish this without the use of a star tracker, just a basic DSLR, lens, and tripod. The second half of the video is a processing tutorial using the free programs Siril and Starnet. ============================= ❤️ Patreon ❤️ ============================= If you like what you see on this channel, consider joining my Patreon.
