I was out on Friday for a bit over 2 hours. It wasn't too bad. I mostly got cold in the pants, I'll need to get some good bibs. And my breath froze to anything around my face, including eyelashes. I did get some good data though, of M42. I'll post it in the images section. I could've probably stayed out quite a bit longer as no part of me was getting numb, but the equipment wasn't liking the cold much.
