The two brightest comets currently visible in the sky, C/2025 R2 (SWAN) and C/2025 A6 (Lemmon), captured last weekend with an ASI294mc Pro on my C8. #Comet Lemmon is already bidding farewell to the northern hemisphere, so I had to catch it in the near-horizon haze. #astrophotography 🔭

The planetary nebula Sh2-188 in the constellation Cassiopeia is also known as Shrimp Nebula due to its shape. I took this image over five nights in August using a C8, an ASI294mc Pro camera and a total exposure time of around 13 hours (details in image) #Astrophotography

At the end of September, we went #birdwatching in Donana National Park in Spain. Here is a small selection of the birds I photographed there: one of many Hoopoes, a very curious Short-toed Snake Eagle and a Yellow-crowned Weaver.

Comet C/2025 A6 (Lemmon) taken on 19 October from the roof of our garage at 135 mm focal length (stack of 192 10s-subs). Despite thin clouds and streetlights between the comet and me, the gas & dust tails are clearly visible in different colors. Brings back memories of Hale-Bopp #astrophotography

That was an exciting evening on 18 October: 2 cameras, 2 comets and, to top it off, some #auroraborealis: C/2025 R2 (SWAN) was close to the bright nebulae M16 & M17 and the open clusters NGC6645 & M25 (1. image). Comet C/2025 A6 (Lemmon) tried to hide behind clouds but failed (2.)😉

Comet C/2025 A6 (Lemmon) in the early hours of 3 October, captured through the C8 with an ASI294mc and additionally with a Nikon D5600 and a Tamron 70-200 at a focal length of 130 mm. The #comet was also nice to observe visually and will hopefully brighten significantly. #astrophotography

The Snowglobe Nebula (NGC6781) is a beautiful and rather bright planetary nebula in the constellation Aquila. It is also visually a nice object. In August, I photographed it with an ASI294mc Pro through my C8 with a total exposure time of 5 hours. #astrophotography

The Bubble Nebula (NGC 7635) in Cassiopeia was my first target with the new ASI294mc Pro camera. In total, I accumulated a good 8.5 hours of exposure time over 8 nights from our terrasse and am really happy with the result (techn. details in picture) #astrophotography

The spiral galaxy NGC 6946 is known as the Fireworks Galaxy due to its high rate of supernovae. I captured it through my C8 over 6 nights in June & July – actually just as a test of the astro camera that @astrophil.de lent me (technical details in image)

Over the course of 7 nights in May and June, I took test images of the Hercules cluster M13 with the ASI183mc Pro camera, which was kindly provided by @astrophil.de. Also tested different filters, and I'm quite happy with the final stack of all frames #astrophotography @kat-astro-bot.bsky.social

It's Milky Way season. So I went up on our garage roof when the street lights were finally switched off and took some photos. This one is a composite of 120 s for the landscape and 15 x 8 s for the sky (Nikon D5600 + Sigma 18-35 at 18 mm, f/2.8, ISO1600). #astrophotography

In 10 nights in April and May I photographed the Antennae galaxies in the constellation Corvus. The exposure time was just a good 9 hours, as the galaxies only appear briefly above the Harz mountains. At least their "antennae" are faintly visible... #astrophotography

The pretty spiral galaxy NGC5033 is located in the constellation Canes Venatici and is also called Waterbug Galaxy. I collected 11.5 h of exposure time in 7 nights. The photo shows the expanded spiral arms, but visually I could only see the bright centre #astrophotography @kat-astro-bot.bsky.social

Planet #Mars just passed the Beehive cluster (Messier 44) and is still close to it. I could take this photo on April 30 with a focal length of 135 mm (336 x 10s). Unfortunately, it was cloudy on the following days when the distance was at its smallest. #astrophotography @kat-astro-bot.bsky.social 🔭

The barred spiral galaxy NGC 3718 is located in the constellation Ursa Major and was my target for 5 nights in spring. To the east of NGC 3718 is the galaxy NGC 3729, to the south the galaxy group Hickson 56 (technical details in the image). @kat-astro-bot.bsky.social

Hubble's Variable Nebula (NGC 2261) is one of my favorite objects to observe and photograph. This reflection nebula in the constellation Monoceros changes its appearance over time and therefore looks slightly different every season. Took the image with a C8 in February (~7 h). #astrophotography 🔭

The asteroid (8) Flora passed in front of the Hamburger Galaxy (NGC 3628) on 10 April, recognizable as a bright dot in front of the galaxy center. On the night of 13 April, we captured the Werla Castle in the light of the full moon, surrounded by flowering sloe bushes. #astrophotography 🔭

In spring, we observed Nandus (Rhea americana) in northern Germany. Since a few birds escaped from a farm 25 years ago, a wild population has established itself. We also saw Mute, Whooper & Tundra Swans together with Greater White-fronted, Bean & Greylag Geese (all in 3. image) #BirdsSeenIn2025 🦉

The moon visiting the Pleiades - just half an hour ago. Later, the moon will be occulting this open star cluster, so look up. 😃
