Technical details: Location / Date: Outside of Kopparberg, Västmanland, Sweden / 2017-August Optics: Orion Optics UK AG12 Mount: 10 Micron GM1000 HPS (Unguided) Camera: Atik One 6.0 with Astrodon 1,25" L-RGB Gen 2 E-Series Filterser Exposure: L:36 x 240s, R: 5 x 240s, G:5 x 240s, B:5 x 240s (cumulative exposure time is 3 hours and 24 minutes) Processing: Pixinsight and Photoshop   Image details: Cosmic clouds form fantastic shapes in the central regions of emission nebula IC 1805 (The Heart Nebula). The clouds are sculpted by stellar winds and radiation from massive hot stars in the nebula's newborn star cluster, Melotte 15. About 1.5 million years young, the cluster stars are toward the right in this image, along with dark dust clouds in silhouette against glowing atomic gas. Melotte 15 is located about 7,500 light years away toward the boastful constellation Cassiopeia. (Information from APOD)
