scope would have worked better than irons for sure on that shot.
Maybe. Probably, now I think of it. It was pretty danged dark out there!
I once spotted a dark lump under the bow of the boat during a driving rain storm, from my bedroom window, in not as dark conditions as the moose. Could not make it out, but with the binocs, I could barely tell it was a young brown bear taking a nap out of the rain. So yeah.
