Object: The Triangulum Galaxy – M33 (2017)
(Messier 33 or NGC 598)
M33 is a spiral galaxy in our “local group” of galaxies and is located in the constellation of Triangulum. Located about 3000 light-years away it is the 3rd largest galaxy in our local group after Andromeda and our galaxy and is sometimes referred to as the pinwheel galaxy, a nickname is shares with M101. M33 contains about 40 billion stars, has a mass of 50 trillion solar masses and it about 50,000 light years across.

Object: Markarian’s Chain – 2022

Markarian's Chain is a grouping of galaxies that forms part of the Virgo Cluster. When viewed from Earth, the galaxies lie along a smoothly curved line. At least seven galaxies in the chain appear to move in concert, although others appear to be positioned by chance.

Near the center of the chain of there appear the pair of interacting galaxies NGC 4438 and NGC 4435, about 50 million light-years away, known to some as Markarian's Eyes or simply The Eyes
