Orion's Belt - Snake Valley

This is the best I could do wide field with the weather at Snake Valley. Missed out on the last night of the camp, which was clear by all accounts.

Look closely and you will immediately notice a of lack data. 60 mins 180 second dithered, unguided subs @ iso800 and 0 Celsius with my cooled 450D. The usual compliment of bias dark and flats.

The spikes here and there are from a wire across the observing field. Thought I was low enough to miss it...

Might try this one without darks and see if that improves the noise - have a feeling darks may be contributing in this case...
