On this page I collect my observations of the elliptical galaxy NGC 3842 in the constellation Leo, the brightest galaxy in the galaxy cluster Abell 1637, also called Leo Cluster. On the eVscope photo, you can find a number of other galaxies (also with the help of nova.astrometry.net).
The elliptical galaxy NGC 3842 in the constellation Leo is the brightest galaxy in the galaxy cluster Abell 1637, also called Leo Cluster.
The Leo Cluster (Abell 1367) is a galaxy cluster about 330 million light-years distant in the constellation Leo, with at least 70 major galaxies. The galaxy known as NGC 3842 is the brightest member of this cluster. Along with the Coma Cluster, it is one of the two major clusters comprising the Coma Supercluster (Wikipedia).
According to Wikipedia, the largest members of Abell 1637 are: NGC 3842, NGC 3883, NGC 3884, NGC 3861A and B, NGC 3837, UGC 6697, NGC 3862, NGC 3864. All in all, the Leo Cluster comprises more than 500 galaxies.
On an eVscope photo, I was able to find a number of (10) other galaxies with the help of nova.astrometry.net: NGC 3861, NGC 3860, NGC 3837, NGC 3851, NGC 3842, NGC 3841, NGC 3845, NGC 3844, NGC 3840, UGC 6697.
