Sorry, should have included more details. It was the Vixen 200mm, QHY10, CGEM mount, etc. But at the end of it all the data I collected was that bad you'd just delete it normally if it wasn't for the reason I tried to get it..
I got the idea from a post here on IIS:

Here's pic of what I meant by ice, I had to leave the mount out in the middle of a paddock because it's too heavy to lug back inside across uneven ground in the dark. This was about 7am this morning, it was like that while imaging.
