10 days old moon through 72 year old telescope

A late friend of mine owned a Zeiss AS 63mm lens, it took me a while to figure out all the details, as it is not mounted in the original cell, but in a custom machined one, and the tube loooks like it is self-built too.

In the process of establishing the quality of the lens I took these images with a QHY5L-IIc camera in prime focus configuration. As the conditions were very changeable because of passing clouds, the brightness of the images had to be adjusted individually, color saturation has been enhanced.

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.

Taurus Molecular Cloud with 85mm

Taurus Molecular Cloud, California Nebula NGC1499 and Plejades M45, 120x30s, ISO3200, Nikon Z6, Nikkor S 85mm f/1.8 at f/1.8 processed in Fitswork, Photoshop, Lightroom

I tried to use a break in the clouds to photograph a long-time favourit of mine, the Taurus Molecular Cloud TMC. The conditions were far from optimal with some slight fog and clouds passing through, but after throwing away quite a few frames, I ended up with this version.

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.
