Currently, #comet 10P/Temple is at its brightest, though it can only be seen just above the horizon. I took this shot on 24 July through my C8 (23 x 2 mins) using an UV/IR cut filter. With the display set to full brightness, you can just make out the dust tail. #astrophotography 🔭 1/2
The Coma Cluster (Abell 1656) consists of over 1,000 #galaxies and is about 300 million light-years away. I captured it over the course of 8 nights from April to June (about 9.5 h exposure), but processing turned out to be challenging. How many galaxies can you spot @kat-astro-bot.bsky.social? 🔭
The beautiful spiral galaxy NGC 2403 in the constellation Camelopardalis was my ‘spring project’. The #galaxy contains many HII regions, which is why I combined data taken with the Optolong L-Pro and the IDAS NB12 filter (just under 5 hours each). #astrophotography 🔭 @kat-astro-bot.bsky.social
In the Camargue, we saw many Spotted Redshanks resting there on their migration to their Scandinavian breeding grounds. In a few weeks’ time, they will already be heading south again... 🪶 #birdmigration #birdwatching #NaturePhotography #BirdsSeenIn2026
Back in April, we were able to observe many Greater Flamingos in the Camargue. In fact, they were in almost every body of water and weren't shy at all... 🦩 #FlamingoFriday 🪶 #birdwatching #NaturePhotography
Abell 1656 - The Coma Cluster captured from my dark site in southern France in April 🇫🇷😊🔭 This was shot on the EdgeHD 8 with Hyperstar at f/2 for a total integration time of 4 hours using a QHY183C cam without any filter. #Astrophotography @kat-astro-bot.bsky.social how many galaxies do you see?
In April, #comet C/2025 R3 (PanSTARRS) was easy to observe in the morning sky. At the time, we were in the Camargue, where I was able to photograph the comet at dawn. The final image is a stack of 179 x 6-second exposures at 150 mm, processed with & without background extraction 🔭 #astrophotography
Some of the birds we spotted in the Camargue back in April: a very curious Sardinian Warbler, a Chiffchaff and a Cattle Egret in its breeding plumage. Definitely a great region for #birdwatching 🪶 #NaturePhotography #BirdsSeenIn2026 #France
Over the past few days, planet #Venus passed between the two open star clusters of the #Pleiades and the #Hyades. A beautiful constellation after sunset, that I was able to capture on April 25 and 26 over a lake and a rapeseed field, respectively. #astrophotography 🔭
The Horsehead Nebula (IC 434) was my little side project in late winter; the total exposure time of this image is 7h 49min (North is left). Processing turned out to be surprisingly difficult, since the nearby star Alnitak left a lot of reflections in the field of view 🔭 @kat-astro-bot.bsky.social
NGC 3344 - The Sliced Onion Galaxy captured from my patio on seven nights this month 😊🔭 It was shot on the EdgeHD 8 for a total integration time of about 46 hours in LRGB and Ha to reveal the star forming regions. #Astrophotography @kat-astro-bot.bsky.social what do you see?
The Leo Triplet is a small group of galaxies bound together by gravity in the constellation Leo. It lies approximately 35 million light-years from Earth and consists of three prominent spiral galaxies: Messier 65, Messier 66 and NGC 3628. Captured over two nights in March 2026. #Astrophotography
Two of the currently visible comets: C/2024 E1 (Wierzchos) and 24P/Schaumasse, taken with an ASI294mc Pro through my C8 on 5 & 12 March, respectively (techn. details in images). No "pretty pictures" due to dust and light pollution, but at least two interesting objects for #astrophotography. #comet 🔭
In February, the #supernova SN2026dix flared up in the spiral galaxy NGC 3913. I captured it along with the galaxies NGC 3916 and 3921 on 8 & 9 March using my C8, but conditions were rather unfavourable due to Saharan dust in the atmosphere. #sn2026dix #astrophotography 🔭 @kat-astro-bot.bsky.social
The spiral galaxy M 94 in Canes Venatici is an easy object to observe due to its bright centre with an inner ring of young stars. This photo, which I took over 3 nights in January with an exposure time of 12 h, also shows the faint outer ring of stars. #astrophotography 🔭 @kat-astro-bot.bsky.social
PuWe 1 captured from my dark site in southern France 🇫🇷 😊🔭 This was shot on the EdgeHD 8 with Hyperstar at f/2 for a total integration time of about 6.5 hours using an OSC cam with the Baader UHCL filter. PuWe 1 is one of the largest and faintest planetary nebula known! #Astrophotography
The Crab Nebula (M 1) in the constellation Taurus was the second prominent supernova remnant that I captured this January. It is already visible with larger binoculars, but all the nice filaments only show up in the photo. Total integration: 6h 26min #astrophotography 🔭 @kat-astro-bot.bsky.social
The Jellyfish Nebula (IC 443), a prominent supernova remnant in the constellation Gemini, was my first attempt at a mosaic. The idea only came to me during data collection, but after some challenging editing, I am kind of happy with the result. 🔭 #astrophotography @kat-astro-bot.bsky.social
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
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
