Fabric of the cosmos.

Every few months I get a wild hair to fiddle with astrophotogeekery.  There are heaps of tutorials online to get you in the vague arena of the shot you're after, but in the end you have to get out and make a lot of mistakes while shorting yourself on sleep in order to get anything unique.

The beauty of this niche of photogeeking is that you can never know exactly what you'll end up with--too many variables, too few of them controllable.

The bummer of this niche is that I'm already chronically sleep deprived, and another hobby to get OCD about after dark isn't going to help.

Last weekend I shot some night exposures from deep within the Gunnison Gorge.  The image below was spawned by the simple idea that a non-conventional interval shot might yield something noteworthy.  

I set the lens to 16mm and manual focus at infinity, then set the 7d body to f2.8, ISO 3200, RAW capture, auto white balance, shutter open for 29 seconds, and a 5 minute 5 second interval.

I used StarStax to stitch the 30 resulting images, then did a very basic levels adjustment in iPhoto to arrive at what you see above.

I've not yet gotten to the point with astrophotogeeking where I have expectations of what will result from any given shot or sequence, thus the fabric-esque pattern that resulted here was an unexpected delight.

Thanks for checking in.
