Orion is quickly disappearing from the dark night sky now, as spring begins and the winter constellations depart the sky. This is a shot from February, one I only just now processed.
The Belt of Orion really stands out as do the nebulas that wind all through and around Orion. This is a rich region of the sky for star formation.
I took this portrait of Orion using the 50mm Sigma lens, taking four 5-minute exposures and stacking them. In this case each exposure had varying amounts of haze in the sky as light clouds moved in. So the fuzzy glows around stars are from natural causes here, and are not produced by filters (as in the blog from last year called Fuzzy Constellations) or by post-processing. The glows bring out the star colours, particularly orangish Betelgeuse at upper left and blue Rigel at lower right.
This is the first image I’ve processed using the new Beta version of Photoshop CS6 and Adobe Camera Raw 7 software, just released this past week. Very nice indeed! You can download it for free from Adobe Labs. I like the new interface and functions. I’m not sure the final image quality is any better but some of the new features will be very nice for astrophotography and day to day use. Increased speed is promised but I haven’t seen much evidence for that. But this is a Beta version.
