Happy Thanksgiving from Port Orchard, Washington

Submitted by jimwcoleman

Happy Thanksgiving! The skies in the Seattle area are clear but hazy, due to a pressure inversion. The moon is a day past full and very bright in the sky. Despite that, I photographed the Andromeda Galaxy over Port Orchard, Washington. The Canon 60D was piggybacked atop an 8" Orion Astrograph Newtonian on a Celestron Advanced VX mount. Total exposure time was 45 minutes (15x180 sec subs with 5x180 darks at ISO 1600, 200 mm Canon lens). I would have been able to bring out far more detail on a darker night, but this was the best I could do with what was given to me tonight. :)

Uranus on a crisp, moonlit night

Submitted by jimwcoleman

Here's a view of the planet Uranus. Tonight, the planet is very near the moon and the skies are bright. This image was captured with an Orion G3 Starshoot CCD camera at the business end of an 8" Meade LX200 with a Lepus .62 telecompressor in between. This is 150 four second exposures stacked with Maxim DL. I had to quit when everything iced up.
A careful eye will see artifacts in this image caused by the glare from the nearby moon...

Comet C/2014 Q3 Borisov

Submitted by thenakedastronomer

Here is a photo of Comet C/2014 Q3 Borisov. It is currently magnitude 13.2, which makes it a very dim object in the sky. In this photo (click to enlarge photo of necessary), you can see a “fuzzy blob” near the center of the photo. That is the comet. Orion 8 Astrograph Newtonian, Baader MPCC coma corrector, Canon T3i (modified) at prime focus, f3.9, ISO 1600, 5×23 subs, 3 darks.

IC1396 "The Elephant’s Trunk"

Submitted by thenakedastronomer

The Elephant’s Trunk nebula is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2,400 light years away from Earth.[1] The piece of the nebula shown here is the dark, dense globule IC 1396A; it is commonly called the Elephant’s Trunk nebula because of its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim. Orion 8 Astrograph Newtonian, Baader MPCC coma corrector, Canon T3i (modified) at prime focus, f3.9, ISO 1600, 17×23 subs, 2 darks.

The Great Orion Nebula

Submitted by thenakedastronomer

This is Messier 42 (The Great Orion Nebula), a very easy target in the constellation Orion. This time of year, Orion rises over the eastern horizon and is well into the sky by 8 p.m. (Canon T3i at prime focus on an Orion 8″ Astrograph Newtonian, Baader MPCC coma corrector, 10×15 sec subs, ISO 1600, DeepSkyStacker).
