Currently, several weaker comets are at least bright enough to be photographed. I captured 24P/Schaumasse on 17 January and the fragmented #comet C/2025 K1 (ATLAS) back on 26 December 2025. Their very different appearances are definitely worth further observation #astrophotography 🔭

A short time-lapse of yesterday's bright northern lights in the Harz foothills. I'm still thrilled by yesterday's spectacular views – today's #aurora is significantly weaker... #AuroraBorealis #Polarlicht #astrophotography 🔭

Crazy #AuroraBorealis last night at latitude <52° N, even hitting Orion in the southern sky above the Harz mountains. What a night! #astrophotography 🔭

Sh2-234 (IC 417) The Spider Nebula captured from my patio on six nights in December 😊🔭 It was shot on the EdgeHD 8 for a total integration time of about 50 hours in mono using Ha, SII and OIII narrowband filters and combined with RGB stars. #Astrophotography

Finally, here is my composite image of the #Geminids peak on 13/14 December 2025. It was by far my most successful observation of a #MeteorShower, with over 260 meteors within 5 hours - what a night! The image is a composite of 61 individual shots of 15s and contains 65 Geminids. #Astrophotography 🔭

The interstellar #comet #3I/ATLAS is currently visible in the constellation Leo. I took this image on 14 December through my C8 with an ASI294mc Pro. 3I was brighter than I expected at the time, and numerous galaxies are also visible in the background. #astrophotography @kat-astro-bot.bsky.social

That was a tough one: The galaxy M74 in the constellation Pisces (and the weather) gave me some trouble, but I'm quite happy with my final image. This is a combined exposure time of 13 h with the L-Pro & IDAS NB12, which brought out the H-alpha regions #astrophotography @kat-astro-bot.bsky.social

Yesterday morning, I spotted the razor-thin crescent of the 28-day-old #moon just above the horizon. It was invisible to the naked eye, but it was a magnificent view through binoculars. This morning, there was a spectacular #sunrise to enjoy – what a display of colour! 🔭

This is #comet C/2025 K1 (ATLAS) from 11 December with two distinct nucleus fragments. It has changed significantly compared to my image from 22 November - and it has clearly reduced its relative speed, as I was able to expose for a little longer this time... #astrophotography 🔭

Sh2-200 The Bearclaw Nebula captured from my patio on six nights last month 😊🔭 This was shot on the EdgeHD 8 for a total integration time of about 55 hours in mono with Ha and OIII narrowband filters and combined with RGB stars. #Astrophotography @kat-astro-bot.bsky.social‬ what do you see?

A little late to the party, but here's last weekend's sun with massive sunspots, captured with a Nikon D5600 + Tamron 150-600 at 600 mm (f/8; ISO100; stack of 10 x 1/100 s) through thin clouds #astrophotography #sunphotography 🔭

#Comet C/2025 K1 (ATLAS) showed three clearly recognisable fragments of its nucleus on 22 November, and it appeared brighter than I had expected. Due to its fast movement relative to the stars, I could only take 20-second exposures through the C8 (image is a stack of 100 subs) #astrophotography

VdB 14 and VdB 15 captured from my dark site in southern France end of September 🇫🇷 😊🔭 This was shot on the EdgeHD 8 with Hyperstar for a total integration time of about 5.5 hours using an OSC cam with just the UV/IR-Cut filter. #Astrophotography @kat-astro-bot.bsky.social‬ what do you see?

The Pacman Nebula NGC 281 in Cassiopeia had been on my wish list for several years, and now, over the course of 4 nights in September & October, I finally got it. Visually not an easy object due to light pollution, but really fun to photograph (tech. details in image) 🔭 @kat-astro-bot.bsky.social

WR 134 is a Wolf-Rayet star in the constellation Cygnus, surrounded by a ring nebula created by its extreme stellar wind and radiation. The image was taken in July 2025 over several nights and is composed of 70 photos, each with an exposure time of 600 seconds. #Astrophotography

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 @kat-astro-bot.bsky.social

Wolf’s Cave Nebula (LDN 1217 / vdB 152) captured on two nights a couple of weeks ago 😊🔭 This was shot on the EdgeHD 8 with Hyperstar for a total integration time of about 8.5 hours. I combined OSC and mono Ha data for this image. #Astrophotography @kat-astro-bot.bsky.social‬ what do you see?

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. #birds 🦉 #BirdsSeenIn2025

LDN 1165 captured on two nights a couple of weeks ago 😊🔭 This was shot on the EdgeHD 8 with Hyperstar for a total integration time of 7 hours in OSC and Mono. I used the mono Ha data to enhance the red and the luminance details. #Astrophotography @kat-astro-bot.bsky.social‬ what do you see?

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.)😉 #astrophotography

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

LBN 437 The Gecko Nebula captured from my dark site in southern France last month 🇫🇷 😊🔭 It was shot on the EdgeHD 8 with Hyperstar for a total integration time of 8 hours in OSC and Mono. The red nebulosity was enhanced with Ha data. #Astrophotography @kat-astro-bot.bsky.social‬ what do you see?

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 @kat-astro-bot.bsky.social

Some images of yesterday's #LunarEclipse, taken with a Nikon D5600 and a Tamron 150-600 (at 600 mm) at 20:47, 21:22, 21:31 and 21:49 p.m., respectively. It took the #moon quite a while to emerge above the dust, but then the eclipse was great to observe. #astrophotography

WR 134 captured from my patio on 14 nights in July & August 😊🔭 This nebula around the star WR 134 was shot on the EdgeHD 8 for a total integration time of 58 h in mono with Ha and OIII narrowband filters and merged with RGB stars. #Astrophotography @kat-astro-bot.bsky.social‬ what do you see?

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 @kat-astro-bot.bsky.social

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) #astrophotography @kat-astro-bot.bsky.social

Abell 39 captured from my patio on seven nights in June 😊🔭 This bubble like planetary nebula was shot on the EdgeHD 8 for a total integration time of 27 hours in mono using Ha and OIII narrowband filters and RGB filters for the stars. #Astrophotography @kat-astro-bot.bsky.social‬ what do you see?

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

NGC 6543 The Cat’s Eye Nebula captured from my patio on seven nights 😊🔭 This was shot on the EdgeHD 8 for a total integration time of about 27 hours in mono. It’s a combination of Ha and OIII narrowband data with LRGB data for the core and the stars. #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 @kat-astro-bot.bsky.social

M97 The Owl Nebula captured from my patio on several nights in May 😊🔭 It was shot on the EdgeHD 8 for a total integration time of about 22 hours in mono with Ha and OIII narrowband filters and combined with OSC data for the stars. @kat-astro-bot.bsky.social‬ what do you see? #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

M94 The Croc’s Eye Galaxy captured from my dark site in southern France on two nights in early May 😊🔭🇫🇷 This was shot on the EdgeHD 8 with Hyperstar at f/2 for a total integration time of 5 hours using a QHY183C cam without any filter. @kat-astro-bot.bsky.social‬ what do you see? #Astrophotography

What a moonrise last night with a spectacular pollen corona! Let's see how it will look tonight ... #moon #astrophotography 🔭

The Diamond Ring Nebula (Abell 33) is a beautiful planetary nebula in the constellation Hydra that I captured with my C8 from our backyard during six nights in March. The total integration time was 10 h using the IDAS NB12 filter. #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 #astrophotography 🔭

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 🔭

A little #aurora just 45 minutes ago from the Harz mountains in Germany (52° N). That was quite a nice Easter surprise... #Polarlichter #auroraborealis #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. 😃 Nikon D5600 + Tamron 150-600 (at 210 mm); f/5.3; ISO1600; 1s #astrophotography 🔭

Yesterday's partial #SolarEclipse through clouds and two #astrophotography side projects of the previous months: The open cluster NGC 225 with an embedded reflection nebula, also known as Sailboat Cluster, and the Blue Snowball Nebula NGC 7662, both taken through my C8 (technical details in images)🔭

The Medusa Nebula is a large but faint planetary nebula in Gemini that I wasn't sure I could capture under my conditions with all the light pollution. But with nearly 16 h of exposure it shows up nicely through the C8 (technical details in the image) #astrophotography 🔭 @kat-astro-bot.bsky.social

Jones-Emberson 1 captured from my patio on 5 nights last month 😊🔭 It was shot on the EdgeHD 8 for a total integration time of about 34 hours in mono with Ha and OIII narrowband filters and LRGB filters for the stars. #Astrophotography @kat-astro-bot.bsky.social‬
