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.
A 180° panorama from the deck of the Hurtigruten ship the ms Trollfjord, looking northward toward the Northern Lights, as friends Dave and Christine at right gaze at the aurora. This was October 19, 2019, southbound from the coast of Norway north of Tromsø and south of Skjervøy. The Kp Index was 1 to 2 this night. The waning gibbous Moon is low in the southeast at right, lighting the seascape. The Big Dipper and due north is at centre. West is to the left; east to the right. This is a 9-segment panorama with the 15mm lens at f/2 and Sony a7III at ISO 6400 for 0.6 second each and stitched with Adobe Camera Raw.
The Northern Lights in an arc across the northern sky over the Cameron River, downriver from the Ramparts Falls. This was September 8, 2019 with the trees turning in their fall colours. The Big Dipper at top centre. This is a two-segment panorama, each 25 seconds at f/2 with the Laowa 15mm lens and Sony a7III at ISO 800. Stitched with ACR.
