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…
The Butterfly Galaxies
The galaxies NGC4567 and NGC4568 are colliding 60 million light-years away. This is really pushing the resolution limits here; we had good “seeing” last night meaning not a lot of turbulence to smear out the light reaching my telescope, and I carefully collimated and calibrated things prior to imaging last night. About as good as…
Horsehead Nebula
The iconic Horsehead Nebula, near Orion’s belt. Shot in narrowband over two evenings.
M106 and some of its buddies
The galaxy M106 is an interesting one; it’s large and relatively bright – about the same size as Andromeda. And it’s in a busy part of the sky, within Canes Venatici, with lots of galactic neighbors. This image has been enhanced with Hydrogen emission data; that’s what the red dots and tendrils are. There’s one…
The Witch Head Nebula
Lit up by the bright star Rigel in Orion, the “Witch Head Nebula” is a cloud of dust that reflect blue a little bit more. Unlike emission nebulas that emit their own light from ionized gases, this just reflects the light of Orion – although there *is* some ionized Hydrogen in the background, which you’ll…
Orion’s Sword
If you look at the constellation Orion in the winter night’s sky, the center of Orion’s “sword” is not a star at all – it is the brightest nebula in our sky, M42 or the Great Nebula of Orion. Sitting right on top of it is technically another nebula designated M43, and above that is…
