Star trails over Port Orchard

Submitted by jimwcoleman

Here is a time lapse showing the motion of stars over my Port Orchard back yard. There also are three aircraft and at least two shooting stars visible in this photo to the discerning eye. Smoke from my fireplace interfered a bit, giving some of the stars a "dotted" look as the smoke drifted overhead as the winds changed. This image represents 299 30-second exposures at six-second intervals using a Canon 60D, a 10mm Sigma lens at IS0 800 - for the technically inclined. :)

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...
