Andromeda Galaxy. Taken on October 8th, 2024. About 6 hours of 5 min exposures taken with Redcat51 250mm focal length and ASI533MC cooled color Astro camera. Was a relatively clear and dark night close to new moon. However, there was an aurora event going, so rejected a few images in stacking when the background gradient from the aurora was noticeable. No filters used besides an IR cut filter.
Here is the camera setup that night with the aurora clearly visible in the background, also note the distinct shape of the big dipper “cup” visible next to the tree silhouette on the left:
And the following morning: (notice the recently added filter wheel)
A earlier shot from Sept 4, 2022 using OpenAstroTracker, Canon 450D and 135mm Canon lens. Notice the red and blue halos around the stars due to chromatic aberration in the lower quality lens I was using at the time.
