5066 Garradd (1990 MA) A Mars-crossing asteroid was photographed on the second night of the December work. When photographing 50yrs. at a distance from the Big Bear Milky Way-sized spiral galaxy NGC 3675, this came into the picture. The asteroid was discovered by Robert H McNaught at the Siding Springs Observatory on June 22, 1990. The asteroid is named after Gordon John Garradd, an Australian amateur astronomer. Gordon Garradd has found a total of 16 comets and 31 asteroids. He lives outside the electricity grid and uses solar as well as wind power. Garrad has built several telescopes himself...

In addition to a couple of interesting galaxies, Giraffe offers a lot of things for lovers of dimmer objects. This somewhat oval planetary nebula has dark structures around the eye-catching central star.

This rod lens galaxy turned out to be a surprisingly great target and certainly deserves to be even more color photography. The structure looked a bit asymmetrical.

This spiral galaxy does not cause great Joyful Screams. The center stood out clearly but the branches poorly. Longer single exposures come into play if I choose to shoot the subject in the future.

Lens galaxies are not very common subjects for me and this picture well shows why this is the case. The subject is not particularly toned in its features.

29P / (Schwassmann-Wachmann 1) The periodic comet of the Jupiter family was filmed on the second night of the December 2021 campaign. Outbreaks sometimes occur in a comet, which is why we have tried to shoot several times. The comet's orbit is outside Jupiter's orbit and will be close to Jupiter 2037 less than 1au away. Discharges may increase the brightness by 1-5 mag. The size of the large comet's core is 60.4km. At the time of filming, the comet was 4.9628 at its nearest, 4.82au on November 6, 2020. Filming began during the astronomical twilight. 1Picture The sum of the stack by...

The program of the shooting night, which was finally interrupted by the clouds, also accommodated one DS subject photographed in color. In brightness, this cleverly shaped planetary nebula did not celebrate, but even the edge areas were still photographed.

This lens galaxy has the features of a spiral galaxy. The rod, which emerged from the clear core of the object, stood out well, the edges weaker. The second galaxy, NGC 941, stands out as a hazy spot in the image.
