M15 - A different Look! (2024)

Messier 15 is a globular cluster located some 35,000 light-years away in the constellation of Pegasus (a.k.a. The Winged Horse). At an age of roughly 12 billion years, it is one of the oldest globular clusters known. The last time I imaged this was in 2018 so it was time for a revisit. This time around I went after some of the integrated galactic dust (IFN) as well as the very dim hydrogen gas in this region of space. I was very happy to get some of the gas and dust especially since none of this was in any of the subframes.

The cluster itself is much better than my previous versions which was expected since my camera and telescope are better. In addition to the faint gas and dust, the region is rich in colorful stars as well as tiny galaxies such as PGC 66899 (upper left), IC 5115 (middle left), and PGC 66834 - PGC 66835 (lower left). My favorites are PGC 66834 and PGC 66835 which appear to be interacting with each other. A larger aperture scope would bring these out really well.
