The Whale Galaxy and the Hockey Stick Galaxy in RBGHα
The Whale Galaxy (NGC 4631) is an edge-on barred spiral galaxy, which is also a starburst galaxy, and The Hockey Stick Galaxy (Galaxies?, NGC 4656/7) are a pair of interacting galaxies. Both lie in the constellation Canes Venatici, and are estimated to be about 30 million light years away.
This is a combination of previously shot color RGB data with the Atik 314L+ and hydrogen-alpha (Hα) data taken wit an Atik 414-EX monochrome camera and Atik narrowband filter. All were guided exposures with a Celestron Edge HD 9.25" scope at f/2.3 with Hyperstar. Preprocessing done in Nebulosity; stacking, channel combination, and processing done in PixInsight; final touches in Photoshop.
Image scale is 2.5"/pixel.
