SNR G206.9+02.3, The Helmut Kohl Nebula - AstroBin I could not find a name for this one, so I decided to call it “Helmut Kohl” because its shape reminds me of the former German chancellor.

🔭 This is the Super Nova Remnant (SNR) G206.9+2.3. The image was taken from Spain with narrowband filters (Ha and OIII). I couldn't find a nice name for it, so I call it "The Helmut Kohl Nebula". Germans will understand.

🔭 The Triangulum Galaxy, M33 is a beautiful sight. 2.73 million light years from earth it's the third largest galaxy visible. I took this photo using LRGB and Ha filters for about 20 hours.

IC 424 and NGC 2024: Horse Head and Flame - AstroBin An image on AstroBin.

🔭This is classic: the Horse Head and Flame. An amazing object, bright and colorful. IC434 was discovered on a photographic image by Williamina Fleming and reported by E. C. Pickering in 1890.

58h is also quite a lot of integration time :)

W63 - AstroBin An image on AstroBin.

🔭W63 is a supernova remnant located in Cygnus. This narrowband image shows Ha, OIII and SII emissions. This object is large and very faint, I needed more than 70 hours of exposure time overall.

SH2-126, The Gecko - AstroBin An image on AstroBin.

🔭 The Gecko, SH2-126 resembles the head of a gecko. Behind the reflection nebula (cosmic dust), there is a large nebula made of hydrogen, rendered in red.

SH2-98 and Friends - AstroBin An image on AstroBin.

🔭 Afaik SH2-98 doesn't have a nice name and their friends haven't either. SH2-98 is the object on the lower left looking a bit like a rose. I took this on in July and August from Trevinca Skies, Spain.

LDN 886 and Friends - AstroBin This is a very busy area in swan.

There is a lot of stuff going on in Swan... 🔭 This is a narroband image of the area around LBN 886, located in the constellation 🦢. I took this image in July 2025 with my remote telescope in Spain. #astrophotography #astronomy #narrowband #trevincaskies

SH2-101, The Tulip Nebula - AstroBin An image on AstroBin.

🔭Another emission nebula in Cygnus is SH2-101, the Tuli. On top of the tulip on the right side is a pair of stars, a white and yellow one. Besides the yellow one is Cygnus-X1, the first documented black hole.

SH2-91, The other Veil - AstroBin An image on AstroBin.

🔭 SH2-91 looks very similar to the Veil Nebulae in Cygnus Loop, that's why some call it "The other Veil". However it's much fainter. Took this from the remote site Trevinca Skies in Spain.

An image of stars and cosmic nebulae.

🔭 There is a lot going on here: SH2-82, the Little Cocoon Nebula in the center, surrounded by small star clusters and reflexion nebulae. I made this image with my telescope at Trevinca Skies, Spain.

What makes you believe that the EU would be positive about the UK returning? It’s obvious that the EU works better and more efficiently without the UK.

I don‘t want you back.

The Giant Squid Nebula (OU4) was discovered by Nicolas Outters in 2011. A very unusual and beautiful object although quite hard to image. 🔭

🔭 Would you believe there are sharks in space? Not even the sharknado franchise went that far. Voilà: The Shark Nebula, LDN 1235. But don't be afraid, it's actually just stellar dust. And it's about 650 ly away.
