Light pollution: dealing with it.
(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…
Thor’s Helmet
This week’s target was Thor’s Helmet (NGC 2359), an emission nebula in Canis Major a rather distant 12,000 light-years away. It’s formed by a Wolf-Rayet star in its center, which is a crazy-hot star whose immense stellar wind is bunching up and ionizing the gases around it in these complex patterns. It’ll probably go supernova…
Triangulum Galaxy
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.
Space Tulip and a Black Hole!
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…
M94 / The “Cat’s Eye Galaxy”
Sometimes called the “Cat’s Eye Galaxy,” this is M94 – about 16 million light years away in the constellation Canes Venatici. You can barely see its faint outer ring surrounding it here, as well as several very distant background galaxies. It’s notable for challenging our understanding of the universe – it appears to have very…
Late-night planetary imaging.
Imaging the planets requires completely different techniques and equipment than deep-sky stuff, and it’s something I’m not really good at yet. What matters the most is the seeing conditions – how stable the atmosphere is. A big part of taking good planetary images is just having the perseverance to get out there whenever the seeing…
