The data for this image was collected in April but i didn’t get around to processing the image until last week. I was working through a new image processing workflow based on PixInsight. It didn’t really take 6 months to develop the process, it just took that long for me to get around to it.
Bode’s Nebula is in the constellation Ursa Major, and therefore towards the north. Until last year when the trees to the north came down, this target was out of view.
The data was aquired over three nights. However, there were a lot of technical problems (and operator error) so only 2 of the three nights produced usable results. And then only a partial set of the data from the other two nights was acceptable. Still, there is 5hrs of integration time which is enough to produce a reasonable image.
M81 (NGC 3031) Bode’s Galaxy
Face-on spiral galaxy in Ursa Major
Dimensions: 26.9 x 14.1 arc-min
Distance: 11.8 mLy
M82 (NGC 3034) Cigar Galaxy
Edge-on spiral galaxy in Ursa Major
Dimensions: 11.2 x 4.3 arc-min
Distance: 11.4-12.4 mLy
The bright star in the upper middle of M82 is a supernova SN 2014J which appeared 2014-01-21 at 19.20 UT. A close crop with an annotated view shows the location of the super nova.
