A new nova was discovered in the constellation of Delphinus on August 14 18:00 UT. I was able to start imaging within 5 hours of the discovery and gather some nice brightness measurements. Here my latest estimations can be found: The nova is still brightening and now visible with the naked eye. Here is an …
Today there was an item on RTL television about astrophotography and my nomination for the Astrophotographer of the year 2013 competition. It’s in Dutch:
NGC 7331 (in the lower left of the image) is a galaxy similar to our own galaxy in the constellation Pegasus at a distance of about 50 million lightyears. It was discovered in 1784 by William Herschel. Below NGC 7331 a few other galaxies can be seen that are part of the so called Deer …
This was my most elusive target until now. Kronberger 61 is a planetary nebula only discovered in 2011 by an amateur astronomer while searching through the kepler satellite imagery. This nebula has a surface brightness of much less than 25 mag/arcsec^2 and therefore is very hard to detect. This image was made using 30 minute …
Last night I had the opportunity to put my new Astrodon TrueRGB gen2 filters up to the test. I have been imaging Barnard 344 and wanted to get some RGB data for this. Yesterday there was a 94% moon under a very lightpolluted sky (I live in one of the most lightpolluted areas of the …
Barnard 344 is a dark nebula in the constellation of Cygnus. It’s located close to the star Sadr in the Gamma Cygni Nebula. Barnard 344 is located on the bottom of the image. This region is very rich of dark and emission nebulae. On the image also VanDenBergh 130, a reflection nebula in this region, …
Barnard 344 is a dark nebula in the constellation of Cygnus. It’s located close to the star Sadr in the Gamma Cygni Nebula. Barnard 344 is located on the bottom of the image. (An annotated version can be seen here.) This region is very rich of dark and emission nebulae. On the image also VanDenBergh …
NGC 7000 is also known as the North America Nebula with the so called Gulf of Mexico. In this area the Cygnus Wall can be found. This part is the Mexican and Middle American part of the Nebula. It’s one of the most interesting parts of the nebula because this is a region of active …

Click on image for high resolution The nebula Sh2-101 is better known as the Tulip Nebula. This nebula is strong in H-alpha emissions. The nebula has a distance of about 2000 lightyears from Earth. This image also shows the famous Cygnus X-1 system. Cygnus X-1 is the brightest source of hard X-rays in our sky. …
