🔭 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.

🔭 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.

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

🔭NGC 7023, aka the Iris Nebula, is a bright reflection nebula in the constellation Cepheus, where starlight from a young star illuminates surrounding interstellar dust, creating a vivid, flower-like glow. Image taken from trevincaskies.com, Spain.

🔭 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.

🔭There's a Monkey Head in the night sky: #NGC2174, about 6400 light years away. I took this from my backyard in Berlin and removed the stars, so the nebula pops out more. The image was taken by only recording light emitted by Ha, OIII and SII particles, aka "narrowband imaging". 🔭
