This is my first “dark nebula” – a cloud of dark dust obscuring the Milky Way behind it. You need dark skies to capture these things, which my remote setup in central Texas now provides. Well, at least when the moon isn’t up. Formally LDN1235, this is actually a much larger object that extends further…

(Image credit: ddmitr, iStockPhoto.com) Every picture on this site was taken from a suburban driveway in a “red zone” on the light pollution map, literally underneath a streetlight. Every year more subdivisions and apartment buildings spring up in my city, and light pollution from the metro Orlando area just keeps getting worse. There are four…

This gorgeous nebula, formally known as NGC281 in the constellation Cassiopeia, goes by the informal name of “The Pac-Man Nebula.” I don’t see a Pac-Man. I think it’s a case where if you look at it through a telescope with your eyes, you only see the brightest parts – and then, maybe it looks a…

In these short summer nights, I want to take advantage of every moment of darkness. Right now, the galaxy M100 is up in the hours before midnight, and the “Tulip Nebula” – formally SH2-101 – rises just as M100 sets. So for this past week, I’ve been imaging both objects. But no more clear skies…

Part of our Local Group of galaxies, the Triangulum Galaxy (M33) is about 3 million light years away and the most distant object visible to the naked eye under dark skies.

Somehow I’ve neglected to go back to one of the showcase galaxies of the spring sky with newer equipment and software: M101, the “Pinwheel Galaxy.” Located about 21 million light-years away within Ursa Major, this relatively close galaxy shows lots of active star-forming regions revealed by red HII gas. Those red spots are nebulae in…
