Here we have another globular cluster: M53. You don’t see this one imaged too often, but it’s still quite pretty. I’ve never met a globular cluster I didn’t like. It’s one of the more distant globular clusters in our galaxy, about 60,000 light-years away.

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…

This is the Tulip Nebula in Cygnus, but see that shell-like structure just above it, to the right a little? That’s the bow shock wave of Cygnus X-1, a stellar-mass black hole! It’s one of the most powerful X-ray sources in the sky – but don’t worry, our atmosphere protects you from it. 20 hours…

This was intended to just be an image of the galaxy M77 in Cetus, but quite a few other galactic photobombers showed up! The annotated image below guides you to the brighter galaxies in this image, but click on it to expand it, and you’ll find many other ones as well that are incomprehensibly distant.

Here’s 20 hours of exposure time on the Pleiades in Taurus… a lot of people call this the “little dipper” since it does look like a tiny one to the eye, but the little dipper is a larger constellation. Although it’s known as the “seven sisters,” in fact it’s a cluster of a thousand or…

This portion of the North America Nebula in the constellation – you guessed it – Cygnus, is a giant cloud of ionized gases where new stars are being created. It’s also pretty. These are both false color images, processed a couple of different ways. The first is the classic “Hubble Palette” that maps ionized emissions…
