NGC 7822 is a young star forming complex in the constellation of Cepheus. The complex encompasses the emission region designated Sharpless 171, and the young cluster of stars named Berkeley 59. The complex is believed to be some 800-1000 pc distant, with the younger components aged no more than a few million years. The complex …
Sometimes you decide to make an image of a region of the sky and it just comes out exactly as you had hoped for. This was one of these moments for me. I decided a while back to image the Gamma Cygni Nebula around the star Sadr in the constellation of Cygnus. I knew …
This is a continuation of a project I started about 2,5 years ago when I worked on a mosaic of Messier 106, made using images of the Hubble Space Telescope. In 2015 I found some new data sources on the internet, including some huge telescope databases with data from professional telescopes. That’s when I decided …
This image is a continuation of an image I made in 2014 of the M81/82 galaxy group. I made the images and found signals of integrated flux nebula surrounding the galaxies. Soon after that I got in touch with Neil Fleming who had a splendid image of the IFN in this region on his website …
Stars are forming in the Soul of the Queen of Aethopia. More specifically, a large star forming region called the Soul Nebula can be found in the direction of the constellation Cassiopeia, who Greek mythology credits as the vain wife of a King who long ago ruled lands surrounding the upper Nile river. The …
A few months ago I was crawling through the Canada-France-Hawaii Telescope (CFHT) data and found this very nice dataset of the Draco Triplet. I decided to download it for later use. Now I processed the data and this is the result of the processing. As far as I know this is the image of the …
Recently I enjoyed my holidays in Vandans, Austria. Just before this holiday I could pick up a Nikon D810a from Nikon HQ to try it out for 3 weeks. Of course I don’t say no to that. This is a brand new camera that was handpicked and calibrated manually by Nikon (a so-called QC model). …
This image was taken on several clear nights between 03/06 – 11/06/2015. Images were taken by myself with my TMB92 and by Tim Schuurman (a fellow astrophotographer) with his 20cm Newton telescope. At the center of the image two blue reflection nebulae are visible. The one on the upper right is called VdB131, the central …

Last night we had a great lecture from Hanny Van Arkel at the Vereniging Christiaan Huygens in Papendrecht. She discovered a new kind of astronomical object in 2007 using the Galaxy Zoo. The class of objects is now called officially ´Hanny´s voorwerp (HsV)´ which is a great achievement I think. One hypothesis suggests that HsV …
