In the night from Saturday August 12th to Sunday August 13th this year was the Perseids peak. The weather was actually the whole week before not inviting. On Saturday, on top of that, it was also completely rainy and very gloomy with dense clouds in the sky. However, almost all weather apps agreed that it […]

DWARF II
First Light with the DWARF II. This all-in-one device is not as problem-free as it is often portrayed. Now and then the software goes on strike, but when it works, the little device positions itself quite accurately and then tracks the object in the sky quite precisely. However, I had only taken a few test […]
M51 – Whirlpool Galaxy
Last night it was finally clear again. However, the moon was also meanwhile back to 89% and on top of that quite windy. The focal length of my telescope is quite short for such objects. Shown above is a crop which was upsampled afterwards. The (almost) uncropped image looks like this. Recording data […]
Spaghetti al Pomodoro
No, not a delicious pasta recipe but the so-called Spaghetti Nebula was my object last night. Since the exposure time was only about 3.5 hours at aperture 2, it is of course not comparable with other images (usually from about 10 hours exposure time). But I am still quite satisfied with the result. The […]
Rosette-Nebula
Last night it was finally clear again; at least until about 11 pm. An opportunity to photograph the Rosette Nebula NGC 2244. Originally I didn’t think that with “only” 2.5 hours exposure time I would get much out of it, but I was proved wrong. OK, more is always good, but here in the north […]
M81/M82 – Bode Nebula
Actually, it was supposed to be the Rosette Nebula, but the full moon in almost the same direction made me choose another object. It became – like a few times before – the M81/M82 galaxy group. In contrast to the longer focal length earlier, the galaxy NGC3077 is also in the picture here. Recording […]
C/2022 E3 (ZTF)
In the night of 7 February to 8 February 2023, I had another opportunity to photograph the comet. This time I used my astro equipment. Tracking was great and the ZWO ASI183 MC also provided the better image quality. With the shots, the processing in Pixinsight also succeeded perfectly, which I didn’t manage at […]
Sunspots
Two (single) shots from yesterday morning with the Fuji X-T5 on the Nikkor 500mm. The first picture was taken with the 1.7 teleconverter on the Nikkor. So the focal length is 850mm. The second one was taken with the Nikkor and a Kenko 2.0 plus a Kenko 1.5 teleconverter. That gives a focal length […]
Astro images reprocessed
With more progress in editing, it is also worthwhile – in case of persistent bad weather – to reprocess some previous shots. In the new edits, the image detail was not chosen 100% exactly the same. Here are some comparisons… M31 – Andromeda from October 7, 2022. M33 – Triangulum Galaxy from […]
Leo-Triplett
Today I integrated the existing images of the Leo Triplet from 2020 and reprocessed them. The result can be seen quite well. A total of 161 exposures with the Nikon D5200 with Kenko 1.5 converter and the Skywatcher 130/650 PDS at ISO 800 and 75 exposures without the Kenko at ISO 1600 (plus corresponding […]
