First off the rank this season with the Dumbbell.
I wasn't going to use the 550d yet, but the temp dropped so fast in the early hours of this morning I thought I may as well see how she performs. (this model will only take acceptable images when the temp is below 10C)
1 1/2 hours of 5min subs, Canon 550d and ED80.
Unfortunately I forgot to switch the camera over to Raw after taking some happy snaps of the mount earlier in the evening.
grrrrr
The temp ended up getting down to 2C.
The first taste of Winter.
If you're heading up to Astrofest, bring yer woolies with you.
