• Description: Imaged from Bortle 9 City of Calgary AB Canada which creates difficult background gradients on such a wide field. As such, the 2.25hrs of unfiltered exposures were combined with 1.4hrs of Anti-Light Pollution filtered exposures to help clean up the background. Even so, faint NGC2672 and NGC2673 galaxy pair can just be seen in the lower left.
