04_Comet_McNaught_1.jpg Canon 10D 70-300 @ 155mm f/4.5 1/45 sec ISO 400br/ 20070112 00:22 UT. Edmonton, Alberta. A beautiful comet, just a simple camera on a tripod! This is as easy as it gets in the modern digital age while waiting for something bigger and brighter! I walked to the schoolyard a couple of blocks away to get the low horizon.
