This image is a stack of the best of 180 30-second subs of Auriga, taken using a Helios 44 58 (58mm) prime lens. I stopped the lens down but stars at the corners are still slightly elongated. I used one of Steve's Astro Actions to correct the three brightest, the smaller ones don't spoil the overall effect. I used a moon and skyglow filter as I suffer moderate LP.
The camera was a cooled Canon 450D. A handwarmer sachet was used to keep the lens clear, although it seems humidity was very low on what was a VERY cold night.
While the wonderful clusters of young, blue stars showed up really well, the flaming star nebula was more difficult to capture on such short subs.
One of the frames included a sole Geminid meteor. This frame was processed separately aiming for a good colour balance, aligned carefully and the meteor trail layered in. The trail starts yellowish, turns blue and fades back to yellow.
On seeing just how crowded the stars are in this part of the sky, I was reminded of Isaac Asimov's novel, The Stars, Like Dust, although it's set near the Horsehead Nebula where there is more dust than stars!
6 hours of 30 second images. The gaps in the trails are from clouds drifting through

anyone care to reverse engineer the waveform so I can hear what the star trail sounds like?
and the timelapse from the same images, best watched on Youtube
