SN2014J

A supernova was discovered in galaxy M82 during mid-January 2014. It was discovered by Steve Fossey of University College London. On 31st January the supernova stopped brightening at a peak magnitude of 10.5, it is the closest Type 1a supernova to be discovered in the past 40 years. Designated as SN 2014J is a type 1a supernova which occurs in a binary system (2 stars orbiting each other) one...


NGC2264 – The Cone Nebula

The Cone Nebula (NGC2264) was discovered in 1785 by William Herschel. It can be found at a distance of 2.600 light years in the northern part of the constellation Monoceros. The Cone Nebula is an extensive nebula region surrounding the so called “Christmas Tree Cluster” and it is a part of a much larger complex which is currently actively forming new stars. NGC2264 refers to both the nebul...


NGC1746

NGC 1746 is an asterism or open cluster in the constellation Taurus, it was discovered in 1828. What you are actually looking at is not a single cluster but an optical grouping of stars belonging to three different clusters which just happen to be in the exact same spot in space when seen from our location. In reality they are at a distance of 420, 2.053 and 2.477 light years. The 3 differe...


M42 – The Orion Nebula

The Orion Nebula is the brightest diffuse nebula in the northern sky and also one of the brightest deepsky objects at all. It is easily visible, even under moderately good conditions. It lies at a distance of about 1.300 light years. The nebula is estimated to be approximately 24 light years across. It contains a very young open cluster at the center, known as the Trapezium. This nebul...


Sh2-232

The large central object in this image is Sharpless2-232, it features a prominent dark lane. Sh2-232 is part of the Sh2-235 complex and consists of 4 HII regions, being SH2-231, 232, 233 and 235. All these objects can be found in the constellation Auriga. A total of three Sharpless objects can be found in this image, as well as 2 planetary nebulae. Check the annotated version to find out w...


NGC6871

NGC6871 (in the middle of the image) is a small open star cluster, consisting of no more than 50 member stars. It can be found in the constellation Cygnus. Besides the star cluster in the center, a lot of dark (B146 & 147)and emission nebulae (LBN179, LBN182) can be seen in this image. The large dark area just right of the center of the image is Barnard 146, the "snake like" protrusion bel...


324 Bamberga

Asteroid 324 Bamberga at opposition in September 2013. Being one of the largest known asteroids, with a diameter of about 255 km, its magnitude however varies greatly due to a very high orbital eccentricity. It is brightest on September 13, at magnitude +8.1, after which it fades again beyond visibility in amateur telescopes. It takes 22 years before it reappears at this magnitude. It makes...


Baader 7nm Ha test

Just wanted to do a quick test for the newly purchased Baader 7nm Ha filter. Decided to use NGC 2244, The Rosette Nebula as the target for the new filter. A total of 15 frames of 10 minutes each were (average) combined into this image.

NGC1499 – The California Nebula

NGC1499, also known as the California Nebula (it resembles the outline of this US state), is a large emission nebula with a low surface brightness, which makes it difficult to observe. The nebula is most likely to be illuminated by Xi Persei (the brightest star in the image). The nebula lies at a distance of about 1000 light years, is about 100 light years long (spans about 2.5° of sky) a...


NGC7380 – The Wizard Nebula

At a distance of only 8.000 light years, NGC7380 (The Wizard Nebula) surrounds a newly forming star cluster with gas and dust. The nebula can be found in the constellation Cepheus and was discovered in 1787. It is also known as Sh2-142.
