You're spot on Jonathan regarding the curvature, a consequence of shooting ultrawide. i do my post in Aperture 3, and what it really lacks is lens distortion correction. In regards to the comet, I was 0 for 2 this week. I did manage to bag a keeper at my local knoll, but unfortunately no such luck with that comet.

thanks for the shoutout btaylor. and arnt, i live in Northern California so I'm lucky to have a rich variety of landscapes within a day drive. I have been doing 5 day phototrips with my friends the past 3 yrs, so it's really a blast to go out on a photo road trip with like minded folks. I already have a week lined up for San Diego then a 48 hr road trip to Death Valley a month later.

Here's my salvage shot from last nite when I struck out trying to photograph a comet:
