Recently I have been working on images of M78. I thought it was nice to show the process that is involved to show what I started with and how it ended. This way you can see how the first raw images look like. You would never expect something like this coming out of this… My …
IC 405 (also known as the Flaming Star Nebula, SH 2-229, or Caldwell 31) is an emission/reflection nebula in the constellation Auriga, surrounding the bluish star AE Aurigae. It shines at magnitude +6.0. Its celestial coordinates are RA 05h 16.2m dec +34° 28′. It surrounds the irregular variable star AE Aurigae and is located near the emission …
Barnard 344 is a dark nebula in the constellation of Cygnus. It’s located close to the star Sadr in the Gamma Cygni Nebula (RA: 20h18m57.4s DEC: +40º 40′ 01″). 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, …
Recently an image of M33 was posted on this site made by Michael van Doorn and myself. By searching for some papers on the internet I was able to find databases giving the coordinates of red and yellow hypergiants, post-red hypergiants (supernova progenitors), variable stars and globular clusters in M33. With pixinsight I overlaid these …
Recently I have teamed up with Michael van Doorn to make some imagery of M33. Michael uses a Celestron C11 with Hyperstar at f/2. This setup has a focal length of about 560mm and so does give a wide field with a high sensitivity. We decided to combine the RGB and Ha from the Hyperstar …

“The bright star cluster [known as an “open cluster”] is known as Melotte15 after its discover, Philibert Jacques Melotte (1880-1961). Melotte 15 is embedded within and illuminates the central portion of the much larger glowing nebula identified as IC 1805. The three bright stars in an arc at the center of this image are type …
Recently I found that the images taken for the Digitized Sky Survey around 1990 are about the same image scale as the images I take now with my TEC-140. So I decided to make a comparison between an image from 1990 and 2013 of NGC 7331 and Stephan’s quintet. It clearly shows the stars are …
Here is a nice image comparison of 1990 Digital Sky Survey data and my image of 16th August 2013: Here an animation is shown of the same area before and after the nova:
