Globular Star Clustersvon Matthias VölzerAstrophotographyVeröffentlicht am Oktober 28, 2021Oktober 28, 2021Kommentare sind deaktiviert Messier 3 - Globular Star ClusterMessier 13 - Globular Star ClusterBoth images were taken back in April 2020. I reprocessed both now with Astro Pixel Processor, espacially to get use of background neutralization and star color calibration capabilities. Pictures are both taken in full color RGB and just ca. 1,5 hrs of RGB data plus flats and darks each.
