Last night in Ohio it was 5 above and I had a good night of imaging with my G11.? There was a 5 to 10 mph breeze that seemed to keep the mirror on my newtonian from frosting.? Everything went really well with good guiding, etc.? That was the coldest with? this particular mount so thought I would chime in.? When I lived in Alaska several years ago, I frequently imaged in zero to 5 above but I had stripped out the old grease on my then mount (Meade LXD75) and replaced the green goo with white lithium grease.? I'm loving my G11.? By the way, the mount is outside but I control it from inside!
