NGC 1499, the California Nebula, in Perseus. This visually faint emission nebula (but easy to capture with a camera) shines above the hot blue star Zeta Persei, aka Menkib, and is surrounded by other faint threshold nebulosity. This is a stack of 8 x 8-minute exposures through the Borg 77mm f/4 astrograph and with the Canon EOS Ra red-sensitive mirrorless camera, at ISO 800. Stacked, aligned and processed in Adobe Camera Raw and Photoshop 2020. No nebula or light pollution reduction filter was employed in taking the images. I shot this from home November 25, 2019 on a very fine if frosty autumn night. The Dew Destroyer heater coil from David Lane wrapped around the front objective lens nicely kept off the frost.
