M52+NGC7635 - 2025-07
M52, an open star cluster, and NGC 7635, an emission nebula, lie within about 2 degrees of each other in the constellation, Cassiopeia. This picture combines two image sets captured on consecutive nights, one with a filter designed to enhance the visibility of emission nebulae, and the other without the filter to capture more "natural", vibrant star colors. Captured under dark skies near Goldendale, WA.

Camera: Canon XSi (450D), H-alpha modified
Mount: Astro-Physics Mach1 GTO
Filter: Optolong LenHance
Integration: 100 mins (20 x 5 mins) for each of the two image sets.
