The Whale and Hockey Stick Galaxies in Canes Venatici
The Whale galaxy (NGC 4631) at top left, with its dwarf elliptical companion galaxy NGC 4627, and the Hockey Stick galaxy, NGC 4656 ato lower right. Both of these galaxies are barred spirals but lie edge on to our line of sight.
This is an integrated LRGB image taken with a William Optics FLT110 scope with Flat4, a QHY163M mono camera and Optolong LRGB filters. Approx 100 x 120s frames with each filter. Image sequencing was managed via SGP and PHD2, a Lakeside Astro focuser enabled autofocus and the mount was a Skywatcher AZ EQ6-GT. All post-processing was carried out in PixInsight.
Taken from Prachinburi, Thailand.
