The Denver Astronomical Society Astrophotography Special Interest Group (ASIG) October Member Gallery
Each month, the Astrophotography Special Interest Group (ASIG) of the Denver Astronomical Society gathers to share one of the most inspiring parts of our hobby—the images we’ve captured of the night sky. From stunning galaxies and colorful nebulae to detailed views of the Moon and planets, members present their latest work, talk through how the images were created, and exchange tips, techniques, and stories from behind the lens. It’s a chance to celebrate progress, learn from one another, and stay motivated under the stars.
