IC405 – the flaming star nebula

IC405, IC 417, M38, NGC 1893, NGC 1907, 80x120s, ISO 1600, Nikon Z6, Takahashi FS-60CB, Optolong L-enhance Filter.

The flaming star nebula IC405 is visible at the upper right in this image, it is a cloud of glowing hydrogen excited by the very hot O-type star AE Aurigae. AE Aurigae is believed to be a former member of a multiple star in the trapezium of Orion. When two binary stars got too close to each other, AE Auriga and presumably also Mu Columbae got ejected. It is now a high velocity star just passing through this gaseous region in the constellation Auriga.

IC1848 – Soul nebula

IC1848 – The Soul nebula, 80x180s (4h), Nikon D7000a, Astro-Professinal 80mm ED, 0,8x Reducer.

Sometimes IC1848 is also called the soul nebula, can you see why? This is my longest exposure yet. The 35mm h-alpha filter allowed to bring out the faint nebulosity in spite of the nearly full moon.

Heart Nebula

Heart Nebula, IC 1805, Sharpless 2-190,122x90s (3h 4m), ISO1600, Nikon D7000a, Astro-Professional 80mm f/7 with 0,8x reducer, Optolong L-Pro Filter

IC 1805 is a cloud of glowing hydrogen in the constellation Perseus. The gas is ionized by the hot young stars of the cluster Melotte 15 at the nebula’s center.

M78 and the Monkey’s Head

Barnard’s Loop, Open Cluster NGC 2112, Reflection Nebula M78, Reflection Nebula NGC 2071, 62x120s (2h 4min), Astro-Professional 80mm f/7, 0,8x Astro-Prof. Red., Nikon D7000a, Optolong L-Pro Filter

Even after more than two hours of exposure the image of the reflection nebula M78 and it’s surroundings is quite grainy. This object needs much more exposure. When pushing the raw files to bring out the faint nebulosity the background becomes a bit streaky, therefore I kept the image quite dark.
