Recently I started working on crawling through some science databases of several large telescopes to see what data can be found in these archives. Some of the most interesting archives I found are, amongst others, the Subaru Telescope, the Gemini Telescopes, the Canadian-French-Hawaii-Telescope (CFHT) and of course the Hubble Legacy Archive. This image shows …
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 …
This is my first image with my new TMB-92 telescope. I performed 90% of the processing of this image for the first time in pixinsight. I’m impressed with the capabilities of this software.
Last year (2013) I visited with my wife and children for the first time a holiday house in Daun, Germany. There I got in touch with some of the members of the Astronomische Vereinigung Vulkaneifel (AVV). This group has taken up the responsibility to keep the Hoher List observatory in Schalkenmehren (near Daun) partly working …
This image of M51 was taken over a period of about 4 years. My first image ever taken was of this galaxy and recently I decided to shoot it again. All data from the last 4 years, taken with a C11, Skywatcher ED80, Robtics ED110 and TEC140 were combined to get this result. Further more …
Imagery of M51 taken during the last two nights by myself (luminance) with a TEC-140 and imagery in RGB from beginning this month by Michael Van Doorn (www.dutchastrocolors.com) using his Hyperstar C11. Telescopes: TEC-140 / C11 hyperstar Camera’s: QSI583ws / SXVR-H18 Exposure time: 14h (70×10 min L, 120 min total RGB) The inverted image shows …
NGC 4631 is a big beautiful spiral galaxy seen edge-on (bottom left) only 25 million light-years away towards the small northern constellation Canes Venatici. This galaxy’s slightly distorted wedge shape suggests to some a cosmic herring and to others the popular moniker of The Whale Galaxy. Either way, it is similar in size to our …
Recently I have been working on image data from M81/M82. The image was a combination of my own data together with the data of Michael van Doorn. I had the feeling there should be more possible with this dataset and I found a great image of this region of Neil Fleming. After being in contact …
Recently there was a supernova in M82, the Cigar galaxy. Last 2 nights I could image this supernova together with the ‘sister’ galaxy of M82, which is M81, aka Bode’s galaxy. Michael van Doorn also made images of the same area with his Hyperstar including a lot of H-alpha data. Michael shared his data and I combined …
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 …
