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

The beautiful galaxy NGC 891 in the constellation Andromeda was my target on various nights from August to December 2024. A lot of data was unusable due to fog, but in the end I was able to expose 11 h through my C8 (tech. details in the image) #astrophotography 🔭 @kat-astro-bot.bsky.social

The emission nebula NGC2359 - Thor's Helmet - was my target during 3 nights in December. It has been on my list for quite a while, but the weather and its low position made it challenging. For now, I got nearly 4.5h with my C8 (tech. details in the image) #astrophotography @kat-astro-bot.bsky.social

LBN 782 and LBN 785 captured from my dark site in southern France on December 30th 2024 😊🔭🇫🇷 This was shot on the EdgeHD 8 with Hyperstar at f/2 for a total integration time of about 4.5 hours using a QHY294C cam and the Baader UHCL filter. @kat-astro-bot.bsky.social‬ #Astrophotography

The Pleiades with the catalog designation M45 are an open star cluster in the constellation Taurus. They can be seen with the naked eye and are 444 light years away from us. They are also known as the seven sisters. #Astrophotography

LBN 777 The Baby Eagle Nebula captured from my dark site in southern France end of December 😊🔭🇫🇷 This was shot on the EdgeHD 8 with Hyperstar at f/2 for a total integration time of about 4 hours using a QHY294C cam and the Baader UHCL filter. @kat-astro-bot.bsky.social‬ #Astrophotography

Ein Sperber hat kurz bei uns vorbeigeschaut, die vorher anwesenden Kleinvögel waren aber schneller... Sparrowhawk (Germany) #BirdsSeenIn2025 #birds

Ein Kernbeißer hat unseren Garten besucht und netterweise so lange auf dem Zweig gewartet, bis ich die Kamera hervorgekramt und ihn fotografiert hatte. Hawfinch (Germany) #BirdsSeenIn2025 #birds

Die Saturn-Bedeckung durch den #Mond vor einigen Stunden war ein wirklich enges Rennen gegen die Wolken. Immerhin konnte ich den Austritt des #Saturn am hellen Mondrand durchs Teleskop verfolgen - eine schöne Premiere für mich (Aufnahmedaten im Bild). #astrophotography 🔭

NGC 7822 close-up captured from my patio on 5 nights last month 😊🔭 This was shot on the EdgeHD 8 for a total integration time of about 26 hours in Mono using Baader Ha, SII and OIII narrowband filters and processed in the classic SHO palette with PixInsight. #Astrophotography

Der Planetarische Nebel NGC 40 ist ein schönes Objekt für die Beobachtung mit einem Teleskop, brauchtaberhohe Vergrößerung. Mit der Kamera am C8 hab ich auch seine orangerote Farbe erwischt - hier 4h belichtet (Ende Sept.) bei knapp 1300 mm Brennweite #Astrophotography 🔭

Au cœur de la nébuleuse du cœur : Melotte 15. Image de janvier 2023. @pahcas.bsky.social m’a appris cette semaine qu’on pouvait mettre en évidence l’éclipse d’une étoile binaire sur les images brutes de la session session qui a produit cette image. Je trouve cette info fascinante ! #Astrophotography

SH2-112 captured from my patio on seven nights in September 😊🔭 This was shot on the EdgeHD 8 for a total integration time of about 31 hours in Mono using Baader Ha and SII narrowband filters and an OSC cam for the RGB sky background and the stars. #Astrophotography

A Caspian Tern from our holiday in Spain for #TernTuesday. I took the image in the Bay of Cadiz Natural Park at the end of September #birds 🦉

Zuletzt hab ich zwei sehr verschiedene Galaxien fotografiert: NGC 7479 ist über 100 Mio. Lichtjahre entfernt & trägt wegen der S-Form ihrer Spiralarme den Beinamen Superman-Galaxie. Die diffuse Zwerggalaxie NGC 6822 begleitet dagegen unsere Milchstraße in nur 1,6 Mio. Lichtjahren #astrophotography 🔭

Ein paar Impressionen des Vogelzugs in der Umgebung von Tarifa Ende September / Anfang Oktober: Bei starkem Levante haben sich besonders viele Weißstörche und Zwergadler an der Küste gestaut und versucht, die Straße von Gibraltar zu überqueren #birds

Es ist wieder soweit: Das Sternbild Orion lässt sich in der 2. Nachthälfte beobachten. Von unserer Terrasse aus zieht es genau über dem Harz entlang - hier aufgenommen als Bilderserie mit etwas wilder Wolkenbildung #astrophotography 🔭
