(Because this a night sky, it is dark, so it's best viewed in full screen if you want to see the stars; click on the icon beside 'HD' in the lower right corner)
This time-lapse thing is addictive! :) Now that I've got the dew-on-the-lens problem under control (using an astronomer's dew heater strip) this type of project seems more viable! I decided that this time out, I would focus (he he) on a simple time-lapse of the clouds and stars in the night sky, using a fish-eye lens to add a little more interest. However, as usual, this project was not without some technical challenges; in my zeal to get lots and lots of frames over the course of the night so that I could make a time lapse of reasonable duration, I used 30 sec shutter speed, which resulted in under-exposure of the images. This necessitated batch post-processing of my 980+ frames, which was tedious and time-consuming and introduced a little more noise than I would have liked. I should have shot with higher ISO and let my 60D's outstanding noise reduction do the heavy lifting - oh, well, all a part of the learning process! But to paraphrase the great Ira Glass, who gives us all hope, we need to remember that we will make mistakes as we learn these skills, and the only way to get better, is to do more of it! :)
Several celestial objects can be identified in the vid. Notes from the astronomer:
1. Ursa Major (The Big Dipper) can be seen rotating through the heavens. At the outset, it is in the upper right of the frame, and rotates counter clockwise across the top of the frame, and is to the left of center at 1:10
2. Polaris, which is the tip of the 'handle'of Ursa Minor (The Little Dipper) can be seen about halfway up the frame, above the peak of the 'shed' (which is actually a backyard observatory, housing a 12" Schmidt-Cassegrain telescope). Ursa Minor rotates counter-clockwise around this point, and can be seen throughout the vid.
3. The bright object visible in the left of the frame, descending to the horizon by the 20 sec mark, is Venus.
4. From 20-40 sec, the constellation of Casseiopia (the 'W' shape) can be seen moving through the frame, above the peak of the observatory
5. Several satellites can be seen streaking through the sky at various points, and from the 5-10 sec mark, a couple of planes can be seen moving upwards, from left to right, behind the observatory.
My goal for next time: time-lapse star trails!
