Messier 101 - The Pinwheel Galaxy

Submitted by jimwcoleman

This is M101, the Pinwheel Galaxy, as seen from Port Orchard, Washington through a Meade 115 Series 6000 APO Triplet refractor. This is 32 one-minute subs with nine darks, stacked with DeepSkyStacker. 

This time of year, the Pinwheel Galaxy is high overhead and to the west at nightfall, just "above" the Big Dipper.

I could have done much better with the processing and will try later. Trying to figure out PixInsight and not having much luck, so just ran it through DSS real quick.

M64 - Black Eye Galaxy

Submitted by jimwcoleman

Pictured here is the Black Eye Galaxy (Messier 64). The Black Eye Galaxy (also called Evil Eye Galaxy and designated Messier 64, M64, or NGC 4826) is a relatively isolated spiral galaxy located 17 million light years away in the northern constellation of Coma Berenices.

It is high overhead in the night sky this time of year and a pleasing target for telescopes.

In this case, I used the smallest telescope in my collection - an AstroTech AT72ED refractor. Total exposure time was 17 minutes, 30 seconds at ISO 1600. Three dark frames were subtracted.

NGC 6946 - The Fireworks Galaxy

Submitted by jimwcoleman

NGC 6946 (also tentatively known as the Fireworks Galaxy) is an intermediate spiral galaxy about 22 million light-years away,[3] in the constellations of Cepheus and Cygnus. It was discovered by William Herschel on 9 September 1798. NGC 6946 is highly obscured by interstellar matter of the Milky Way galaxy, as it is quite close to the galactic plane. It's apparent magnitude is -9.6 making it a faint object, but not out of reach of mid- to large-aperture scopes.

M64 - The Black Eye Galaxy

Submitted by jimwcoleman

Viewing was horrible in the Seattle area tonight ... the moon was bright and the skies were very hazy - so much so that there was a ring around the moon most of the night. But I was out working on the equipment and managed to eek out a photo ... this is Messier 64, the Black Eye Galaxy, and a favorite target of mine.

Meade 8" LX200R, Orion G3 Color Starshoot at prime focus, guided by Orion ST-80 and PHD. 6x120sec subs, stacked with MaximDL.

NGC 2903 - a galaxy in Leo

Submitted by jimwcoleman

Here is NGC 2903, a magnitude 9.7 galaxy roughly 20 million miles away in the Constellation Leo the Lion.

To get this photo, I coupled an Orion Starshoot G3 CCD cam to the prime focus of an 8" LX200, guided by a piggy-backed Orion ST-80 and PHD. Over time, I'm seeing some error in declination, so I limited my exposures to 60 seconds, exposed 50 and stacked only 12. As the image is not as sharp as I would like I would suspect collimation, but the scope was collimated only hours before this photo was taken. Therefore, I suspect tracking/guiding.

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. :)

The Great Andromeda Galaxy

Submitted by jimwcoleman

This is the Great Andromeda Galaxy, photographed tonight from my back yard in Port Orchard, Washington, using a 8″ Orion Astrograph Newtonian, eyepiece projection (15mm), Canon T3i, 1600 ISO, 10×15 seconds, f4. I had to keep the exposure times short due to bright moonlight – I was just messing around with eyepiece projection as it’s the first time I’ve ever attempted it with a Newtonian. All the equipment was mounted on a Celestron AVX, 2×4 alignment.
