M15 - A different Look! (2024)

Messier 15 is a glubular 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 the integrated galactic dust (IFN) as well as the very faint 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.
