The two galaxies have come close together and are new receding. There are starburst regions in both and their mutual gravitational attractions continue to disrupt their structures.

The two galaxies (collectively known as the Heron Galaxy) are interacting and have probably already merged once, separated and are now approaching each other again.

IC342 is a large intermediate-spiral galaxy some 10 million light years distant located in the constellation Camelopardalis. Discovered as late as 1892 by William Denning, it is thought to have escaped detection for so long because it is positioned in a dusty area near the equator of the Milky Way, making it difficult to observe. Viewing through the cosmic dust gives it a reddish-brown hue and causes attenuation of its brightness by two magnitudes. Williams Optics Z103 APO refractor, ZWO ASI1600mm camera and Chroma 1.25” LRGB filters. LRGB 120 s exposures 22:30:30:30 and 300 s exposures 40:20:18:2 (clouds intervened!)

Within this region of hydrogen gas, star formation is taking place. 200 mm Ritchey-Chretien reflector.

William Optics Z103 APO refractor, ZWO ASI1600MM Pro camera. The final result is based on five separate master images, taken on the nights of 23, 24, 25 and 26 March 2020 capturing luminance, red, green and blue channels together with emissions in Hα. Total exposure time 20.4 hours, by far my longest project!

The cluster is one of the largest objects in the universe: it is a group of over 1000 galaxies roughly 250 million LY distant. The larger bright galaxy to the left of the image is NGC1275, a prodigious source of X-rays and radio emission. The image is 1.2° wide, approximately 15 million light years. Image with main galaxies marked, upwards of 130! Skywatcher 200PDS 200 mm f/5 Newtonian on NEQ6 mount. Canon 60Da camera.
