Supernova 2019ein a type 1a is located in the lenticular galaxy NGC5353 in the galaxy cluster of Hickson 68. Imaged the night of May 14, 2019.
Annotated image follows.
Leo Triplet (M65, M66, NGC 3628) in my favorite orientation. The galaxies form part of the M66 Group. The three galaxies show signs of gravitational interaction in the past. M66 has drawn out spiral arms that show a high rate of star formation. NGC 3628 has a long tidal tail stream visible in deep exposure image, in addition to it's warped disk in our edge on view.
Messier 81 is a spiral galaxy about half the size of the Milky Galaxy with a diameter of 90,000 light years, lies about 12 million light years away.
Messier 82 has a diameter of 37,000 light years and is classified as a star burst galaxy. It is undergoing rapid star formation most likely caused by gravitational interaction with M81 and NGC 3077.
NGC 3077 is an elliptical galaxy that appears to have been disrupted by M81 and M82. All of these galaxies belong to the Messier 81 galaxy group. One of the closer galaxy groups to our own Local group.
The Hercules Galaxy Cluster or its more more formal designation of Abell 2151, contains some 200 to 300 galaxies located approximately 500 million light years away. Imaged with the Es127 refractor and the Atik 314L+ mono ccd.
This image shows the location of many of the galaxies in this image, there are still others that aren't cataloged.
Abell 1367 is a galaxy cluster located in the constellation of Leo. Located at a distance of 300 million light years, it contains an estimated 70 to 100+ galaxies. Along with the Coma cluster and other galaxies it forms the Coma super cluster, which is part of a larger structure called the Great Wall that stretches hundreds of millions of light years.
The image consists of 300 and 600 second exposures through L/R/G/B filters over several few and far between clear nights with the ED80CFT refractor, and an Atik 314L+ mono ccd camera. Total integration time was 10+ hours.
