Another revisit of an old target, with better gear and better conditions. This is the Pelican Nebula in the constellation Cygnus. Shot in narrowband over one night, and presented in the “Hubble palette”. Two takes – one wider field, and one close-up with the stars removed. In both cases the image is rotated and mirrored…

The larger galaxy in this image goes only by the boring name “M106”, but it’s anything but boring. About 23 million light-years away, M106 is pretty similar to Andromeda in its size and brightness. But M106 is a lot weirder. In addition to its slightly warped shape, M106 is the home of a giant water-vapor…

I wasn’t able to travel to the path of totality, but here from Florida we still had a partial eclipse. Here’s my shot at its peak, viewed through a special solar telescope using a Hydrogen-Alpha filter to bring out all the roiling detail of the sun’s surface. Check out those prominences around the edge!

There are two different clusters of galaxies in this image – the large galaxy you see is NGC 7331, part of the “Deer Lick Galaxy Group.” The smaller galaxies you see surrounding it (sometimes called “The Fleas”) are actually about ten times further away than NGC 7331. In the corner, you’ll see “Stephan’s Quintet,” a…

Officially called M63, this spiral galaxy about 30 million light-years away is part of the same group as the Whirlpool Galaxy.

This galaxy is only known as M74. At 32 million light-years away, it’s about as far as you can get for a halfway decent image taken from Earth. It is a “grand design” face-on spiral galaxy. Look closely and you’ll see a few more galaxies in the background that are much more distant, and therefore…
