Tried my hand at taking pictures of the northern lights above my home. I'm fairly happy with the results, except that the exposure was long enough that it was difficult to handhold without the stars in the background becoming wobbly.
-I'd like to have a bright lens that's wider than a 50mm. Something like a 28 or 35.
-On one hand, a tripod would be nice. On the other hand, it'd make it harder to reposition the camera, and some of those shots were taken on very short notice when the lights suddenly flared up.
-A city wide power failure would be nice when taking pictures outdoors at night.
