Technically this nebula is called IC63, but its common name “The Ghost of Cassiopeia” seems much more timely, given Halloween is just around the corner!
Imaged all night last night, mostly in true colors with some Hydrogen emissions added in to enhance it.
I don’t know why the press has latched onto the name “the green comet” for C/2022 E3 (ZTF) – most comets are green, and it’s too dim to see any color at all if you’re viewing it through binoculars or a telescope. But through 2 hours of total exposure time, the colors do emerge, and…
This nebula goes by the unassuming name of SH2-9. It’s part of a larger complex of clouds known as the Rho Ophiuchi complex, but you don’t often see people focusing on this part of it. It’s a challenge to image from my location, as it’s very low in the sky in a light-polluted direction. There…
M17 is commonly known as the Swan Nebula or the Omega Nebula. From this angle, I think it looks more like a crab – but “Crab Nebula” was taken! Shot over a hazy summer night, with narrowband filters for the gases of the nebula itself, and RGB natural-color filters for the stars. Presented processed with…
Located about 33,600 light-years away within the constellation Pegasus, Messier 15 is a globular cluster – a tight, ancient ball of stars on the outskirts of our galaxy. The Milky Way is surrounded by many such clusters; this one’s special because it’s known to host a rare intermediate-sized black hole at its center, and it…
The three galaxies in the constellation Leo (M65, M66, and NGC3628) are about 31 million light-years away. Each one is being seen from a different angle; the one viewed edge-on is also known as the “Hamburger Galaxy”. Each has been interacting with each other, and distorting the shapes of these galaxies through the complex dance…
This is IC443, commonly known as the “Jellyfish Nebula” for obvious reasons! IC443 is a supernova remnant about 5,000 light-years away. This is a false-color, narrowband image consisting of a total of 20 hours of exposure time.
