Another moc that I modified a while back but didn’t get around to photographing due to too many tasks at hand. Anyways, this time I added a proper RWS on top, although the scale of the M2 on top is still bothering me a bit so except changes for that in the future. For this version I made the back shorter to match a M-ATV, a vehicle I looked for inspiration.
M15 has an apparent visual magnitude of 6.2, which places it at the edge of naked-eye visibility in very dark skies. With binoculars, it appears as a faint, fuzzy patch, while a telescope reveals its densely packed stars. It lies at a distance of about 33,600 light-years from Earth and spans approximately 175 light-years across. This cluster contains over 100,000 stars, including several notable variable stars, and is famous for its exceptionally dense core, which may harbor a rare type of black hole.
M15 Globular cluster and surrounding dust clouds or IFN in the constellation Pegasus. At an estimated 13 billion years old, it is one of the oldest known globular clusters. 36,000 light-years away. Messier 15 an immense swarm of over 100,000 stars. It's one of about 170 globular star clusters that still roam the halo of the Milky Way. Its diameter is about 200 light-years, but more than half its stars are packed into the central 10 light-years or so, making one of the densest concentrations of stars known. Hubble based meassurements of the increasing velocities of M15's central stars are evidence that a massive Black Hole resides at the center of the dense cluster.

The evening of July 16 provided another opportunity to observe beneath Ottawa's Bortle 7 skies, this time focusing on Messier 15, one of the densest and most concentrated globular clusters in the night sky. Observing conditions were mixed, with seeing rated at 3/5 and a smoky haze from regional forest fires hanging over the city. Although the sky remained largely clear, the haze softened the stars and reduced transparency, adding an extra challenge to an already demanding target.
Messier 15 is a globular cluster in the constellation Pegasus. At an estimated 12.0 billion years old, it is one of the oldest known globular clusters. M15 is about 33,600 light-years from Earth, and it has a total luminosity of 360,000 times that of the Sun. Messier 15 is one of the most densely packed globulars known in the Milky Way galaxy. Its core has undergone a contraction known as "core collapse" and it has a central density cusp with an enormous number of stars surrounding what may be a central black hole.

Had this laying around for like what, 5 months? Never got around to uploading it because of school and what not, but here it is, my newest update on Andrew Somers's Bullpup. Project Azazel's WULF LMV was probably what inspired me to updating it, which resulted in me making a complete overhaul of the chasis and the cabin of the vehicle. The result makes me pretty happy tbh, although it's missing a RWS on top and the back could use some more work.

It is heartening that Harriet and M15 have been bonding and sticking together.
It would be a miracle for sure if they have another clutch this season.
