Re: Submissions: 2014 March
A while back I made images of M81/M82 and combined those with images of Michael Van Doorn. This image asked for more detail and I wanted to try to show these two galaxies in their full glory. I found a great image of Neil Fleming and after contact with him we decided to combine our imagery in one ne...

Image of M81/82. Combination of data taken by several setups to bring out the most detail. This image was made from the light-polluted area near the City of Rotterdam in The Netherlands. http://farm6.staticflickr.com/5485/12600916325_3075eb0f1c.jpg M81/82 with SN2014J by Andre vd Hoeven , on Flickr

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.
