I took this photo of the Milky Way (Scorpius region) last Sunday morning at about 2am just after the moon set and before the clouds came in. Taken with Canon 600D and a Tokina 11-16mm lens at 14mm, f/2.8, 120 seconds. Levels and curves was adjusted with LR4.
I took a handfull of images with the idea of stacking them but I found that the sharpest result was achieved with a single image. I did not even subtract a dark frame but I did some noise cancellation with LR4.
I used a home built tracker on a solid tripod to avoid getting star trails in a single exposure. Magic Lantern was used on the Canon to provide a bulb function.
Which of the following two images do you prefer?
