Description

There is something quite surreal standing on top of 11 inches of ice over deep water when the wind is dead-still and you hear the low-cycle gurgle of shifting water and air under the ice reverberating across the lake, like a series of muffled underwater burps. Hard to describe, but a joyous sound to accompany a slow-roll auroral display last night at the 45th parallel. Without a startracker (still on backorder, more than 6 months later), 10 second images were about as long as could tolerated at iso 1600 without some star trailing, even at 14 mm. I think tracking and pixel peeping with a truly guided DSO image stack has made me far more picky with untracked auroral images. M31 is a faint glow on the left, half way up.
