I managed to view it last night with my 15x70 BA8 (averted vision only) but not easy by any means! With the 20x110 it was easier and was glimpsing it direct on as the evening wore on and the galaxy climbed higher in the sky.
This is my first binocular observed SN
I'm in an orange zone and I was able to see it in a pair of (ironically) Nova 22x100 binoculars. It wasn't too hard to find, but it helped that I viewed it through my 18" scope first, so I knew exactly where it was. It was neat to see them in the 22x100's, just to know I could, but the view in the 18" at 170x was amazing!
I think magnification is important. I didn't get out my 15x70s to try, but I imagine I would have struggled, not because of the smaller aperture, but because of the smaller magnification.
