A collection of bright star clusters and colourful nebulas on the border of Cassiopeia and Cepheus. The prominent star cluster at left is Messier 52. The emission nebula to the lower right of it is NGC 7635, aka the Bubble Nebula; above and to the right of it is the small but intense nebula NGC 7538. At upper right of the frame is Sharpless 2-155, aka the Cave Nebula. The diffuse nebula at bottom is Sharpless 2-157, aka the Lobster Claw Nebula, with the small star cluster NGC 7510 near the end of one of its claws. The small star cluster at lower right made yellow by interstellar dust absorption is NGC 7419. 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. No special star masks were employed in processing to enhance star colours or process them separately.
