Re: Submissions: 2014 February

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. In total I got 17.3 hours of imagery for this one. I even detect some IFN (Integrated Flux Nebula) in the image from my very ...

Re: Submissions: 2014 January

This is an image from the Hubble archives that is never published based on this dataset. I really regret this, because I think it's a beautiful set of data with lots of potential. I downloaded the original fits files and used them to generate this Hubble palette image of this area. It reminds me a b...

Re: Submissions: 2014 January

That's a lovely image, Andre. The colors are beautiful and delicate, and the nebula really appears to be "on fire"! The image looks wonderfully three-dimensional. Ann Thank you so much! I have made another version, which I even like more, but that's of course personal :) http://farm4.stat...

LBN234 / VDB130 / Barnard 344

Because of bad weather I started to looking at old data again. I was not so happy with the old HaRGB version of this data so I did a complete reprocessing. 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:...

23 Megapixel M33 widefield

About 3 weeks ago Michael van Doorn and me made images of M33 on the same evening. He took his images with his C11 Hyperstar, a 27 cm reflector with a f-ratio of only 2, allowing him to take very short exposures to gather much color information. At the same time I took images of a smaller field (the...

Stars and clusters in M33

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), Wolf-Rayet stars, variable stars and globular clusters in M33. With pixinsight I overlaid these on the M33 image to show the d...

Proper motion of stars 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 th...
