The Bubble Nebula, NGC 7635, part of a larger HII could, Sharpless 162, in the constellation Cassiopeia with the open cluster 52 in its neighborhood. The “bubble” is produced by the stellar winds from a massive young and hot star, SAO 20575, in its center. The bubble is embedded in a giant molecular cloud that […]
This is the Trifid Nebula, M20, with the open cluster M21, my first test target from the new Astro-Physics 175 mm f/8 Starfire EDF at the Deep Sky West Observatory. Processing was very straight forward, no tricks necessary. Exposure: LRGB, (22,8,9,10) x 600sec Date: 2017-06-14…2017-06-30 Setup: Astro-Physics 175 Starfire with FLI PL16070 Site: Deep Sky […]
The Flaming Star Region, including the Flaming Star Nebula (Sh2-229, IC405), the Tadpole Nebula (Sh2-236, IC410), the Spider Nebula (Sh2-234, IC417), the Fly Nebula (Sh2-237), the Starfish Cluster (M38), and some more stuff. This is a wide field monochrome image using 3 hours of Ha data taken from my backyard in the light-polluted Frankfurt area […]
This is a very wide field monochrome image of the region around the Cone Nebula and the Christmas Tree Cluster. They are sitting in the middle of a much larger emission nebula with lots of structures. Composed of more than 6 hours of Ha data taken from my backyard in the light-polluted Frankfurt area – […]
The central section of the Heart Nebula (IC1805) with the open cluster Melotte 15. The stellar wind and radiation from this cluster of massive host stars, about 1.5 million years young, has sculputured the emission nebula and dark dust clouds into a dramatic scenery. This Ha image was taken from my light-polluted backyard (Bortle class […]
NGC1342 is an impressive open cluster in Perseus with more than 50 stars and an apparent diameter of 15 arc-minutes across and was discovered by William Herschel in 1799. The cluster is dominated by multiple magnitude 8-10 stars lying in a horizontal band. NGC1342 lies at a distance of 1,170 light-years away and is estimated […]
The Pleiades M45 is an open star cluster containing middle-aged hot stars located in the constellation of Taurus. It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye in the night sky. It is dominated by hot blue and extremely luminous stars that have formed within […]
This is NGC7822, a young and star forming region in Cepheus, also containing Sh2-171. Usually a target for false-color narrowband imaging, which nicely highlights the structures and pillars within the cloud. This, however, is a pure LRGB image in ‘natural’ colors. During processing I reduced the green component somewhat, which leads to a cooler colour […]
A quite busy scenery… including the Bubble Nebula NGC7635 together with the open cluster M52 in the upper right, the Lobster Claw Nebula Sh2-157 in the lower left, and NGC7538 in the lower right. This is a two-panel mosaic of Ha, OIII and SII narrowband exposures with a total of 48 hours (!) worth of […]
