Astronomy in the Canadian Arctic
Copyright: Wayne Ngan; Dunlap Institute for Astronomy & Astrophysics, University of Toronto Ellesmere Island, at 80 degrees North in the Canadian High Arctic, is a unique observatory site. At this polar location, the sun is below the horizon throughout the winter, and the 24 hour darkness greatly increases the efficiency of many types of astronomical surveys. Taken in February 2012 by researchers testing the observing conditions at the site, the picture shows a fisheye view of the sky as seen from the roof top of the Ridge Laboratory, an Environment-Canada atmospheric research laboratory located on a 600m-high ridge about 15 km from Eureka, Nunavut. Jupiter and Venus are visible in the middle of the frame. Just outside the image, the researchers deployed two wide field cameras as part of a pioneering survey by Dunlap Institute to search for transiting exoplanets around very bright stars near the North Celestial Pole.

Here you can find a 100% image of the center: This was one of the most difficult image process ever. The extreme dynamic of the bright center to the faint halo and the use with different narrowbandfilter….

And the short summernights are doing the rest.

To see all data of image acquiring visit my website.

Hi Robert, there's also an interesting happening in the upper left of your second picture.

Copyright: Oleg Bryzgalov, Ukraine The Draco Dwarf is a spheroidal galaxy which was discovered by Albert George Wilson of Lowell Observatory in 1954 on photographic plates of the National Geographic Society's Palomar Observatory Sky Survey (POSS). It is part of the local group and a satellite galaxy of the Milky Way galaxy. The Draco Dwarf is situated in the direction of the Draco Constellation at 34.6° above the galactic plane.

Using 5 different nights in June I managed to get just over 7 hours together for a deep image of the Trifid. I was surprised by the amount of stuff around the nebula itself which I think is not often imaged so deep.
