Recently I attended a lecture from Jay Gabany at our national astrophotography meeting about intensifying colors in your images. I decided to work on one of my favorite images to see if I could get more out of it. Especially the star colors and delicate structures in the nebula I like a lot in …
Recently I made images of M101. Color was not perfect yet, but then I got a message from Irving Pieters who offered to share his data. We combined our data and stacked them together. He also had good colordata, with as a result the attached image. Some of the weak structures around M101 already start …
Simeis-147, also known as SH2-240, is a supernova remnant between the constellations of Auriga and Taurus. It is also known as the Spaghetti nebula because of its filamentary structure. It is a not very often imaged object because of several reasons that make it an extremely difficult object for imaging: the remnant spans a region …
Full resolution on Flickr Published on Bad astronomy blog About 2 years ago I worked on a mosaic of Messier 106, made using images of the Hubble Space Telescope. Recently I found some new data sources on the internet, including some huge telescope databases with data from professional telescopes. That’s when I decided to see …
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 …
Somewhere in October I started with gathering some data of M42 with my TMB92. With this scope it was finally possible to get this nebula in my field of view. Weather only didn’t cooperate lately (nicely said). So when it was clear yesterday I did shoot some more data. It is not enough yet for …
Image taken during the star party in Wateren on 25th of August 2014. IC 5146, also know as the Cocoon nebula. Conditions were quite good, with a SQM of 20.6.
NGC7789 aka Caroline’s Rose… NGC 7789 is an open cluster in Cassiopeia that was discovered by Caroline Herschel in 1783. Her brother William Herschel included it in his catalog as H VI.30. This cluster is also known as “The White Rose” Cluster or “Caroline’s Rose” Cluster because when seen visually, the loops of stars and dark …
This image shows the Double Cluster in the constellation of Perseus. The Double Cluster (also known as Caldwell 14) is the common name for the naked-eye open clusters NGC 869 and NGC 884 (often designated h Persei and χ Persei, respectively), which are close together in the constellation Perseus. NGC 869 and NGC 884 both …
