Formally Abell 33 or the even more catchy name PK238+34.1, the “diamond ring nebula” is a planetary nebula – that means it’s the gas blown off by a dying star, not too different from our own sun. This one’s interesting due to its almost perfectly spherical shape, its cyan color from ionized Oxygen gas, and…

I’ve imaged this one before, but for whatever reason I picked up way more detail on it last night. Part of it’s a better camera and better tracking on the telescope mount, but I think conditions may have just been really awesome last night. It’s not normal to have this many good nights for astrophotography…

Had a few hours of clear skies last night, and captured a globular cluster I hadn’t imaged before: M92. It’s a pretty one, and I’m surprised it’s not more popular. It’s in the constellation Hercules, and I suspect it just gets overshadowed by its even more spectacular neighbor, M13. Globular clusters were enshrouded in mystery…

Hope to revisit this under better conditions in the future; but this came out OK considering a bright moon was out the night it was taken. The Pinwheel Galaxy (M101) is near the end of the handle of the Big Dipper in the sky, although physically it is tens of millions of light-years more distant.

You’re looking at about 500,000 stars, balled up just outside of our galaxy. They are ancient; about 8 billion years old.

The Helix Nebula is also known as the Eye of Sauron or the Eye of God.
