The northern autumn constellations rising on a moonlit summer night over the badlands formations at Dinosaur Provincial Park, Alberta, on July 12, 2022, just before local midnight. The image frames the stars of Cassiopeia (upper left), Perseus (at left), Andromeda (centre) and Pegasus (partly cut off at right). Light from the almost Full Moon, a supermoon this night and low in the south, illuminates the sky blue and foreground a warm colour. The Andromeda Galaxy is just visible in the bright sky at centre. This is a blend of a single 20-second untracked exposure for the sky with a stack of 4 x 20-second exposures for the ground, all with the Canon RF15-35mm lens at 23mm and f/4 and Canon Ra at ISO 400. A mild Pro Contrast filter applied to the ground with Nik Collection Color EFX.
The northern autumn constellations of Pegasus (partially seen at right), Andromeda (across the centre), Perseus (at lower left) and Cassiopeia (at upper left) rising over moonlit formations at Dinosaur Provincial Park, Alberta. Illumination is from the waxing gibbous Moon, setting in the southwest so it is providing a warm "bronze-hour" light. The Andromeda Galaxy, M31, is at centre. The star clusters NGC 752, M34 and the Double Cluster are at left, as well as the Perseus OB Association of stars. Some of the small star clusters in Cassiopeia are resolved as well. Some green bands of airglow also tint the sky, otherwise lit blue by the moonlight. The scene provides a nice contrast of warm earth and cool sky tones. Taken July 8, 2022, this is a blend of tracked (for the sky) and untracked (for the ground) exposures — a stack of 2 for the ground but only one for the sky: 2 minutes at f/5.6 and ISO 800 for the ground and 1 minute at f/2.8 and ISO 400 for the sky, all with the RF28-70mm lens at 28mm and Canon R5. A mild Pro Contrast effect filter added to the ground with Nik Collection 5 and a mild Orton glow added to the sky with Luminar AI. The tracker was the Star Adventurer Mini. Noise reduction applied to the single sky image using RC-Astro Noise XTerminator. I didn't take any more sky shots as the Moon was fast setting and disappearing into clouds, so the light for the ground shots taken after the sky shot would be going away soon. Plus clouds were moving into the frame. The mosquitoes enjoyed my presence here this warm July night!
The northern autumn sky and Milky Way rising in the east, plus Jupiter, in Aries in September 2011. Brightening in the sky at right mid-sky is the Gegenschein. This was taken from home, Sept 20, 2011, with Canon 5D MkII and 15mm Canon lens at f/4 for stack of 5 x 6 minute exposures at ISO 800. Foreground is from one frame of the six.
