I am finally finishing my edits from the evening of Jan 20 and the trip home from Colorado. I found the shooting that evening challenging - I used two systems, a Canon 7D Mk II with a SIGMA 300-800 on a large Feisol tripod with a Wimberley head, and a Canon 5D Mk IV with a Canon 500 f4 IS L + a 1.4 TC III on a RRS tripod with a BH-55 head. I really didn't anticipate difficulties because I had shot the eclipse in 2014 without issues. I thought the moon would be low for some reason - maybe 25 degrees elevation, but it turned out to be almost directly overhead, so trying to look through a vewfinder with a body and a large lens almost vertical in the dark and the cold, was fraught with more difficulties. My 7d lost focus when the eclipse became total, as the moon was too dark to AF on, and trying to fous using live view with my camera and lens vertical in the dark with bifocals etc didnt work well. I had focused and turned off AF, but it got bumped or just telescoped due to verticality. I am quite used to using Live View with bright stars, but the darkness of the moon made it much more challenging, trying to crane my neck around low enough and look through a viewfinder..
I had actually thought about buying a SmallHD LCD display to use but thought I wouldnt need it. It would have been a great help, it turns out, and I will aquire one before I try another eclipse shoot.
I knew what exposures to expect from my previous experience, but didnt anticipate focusing issues, but I will know better next time. The fact that it was 15ºF didn't help either I suspect.
Anyway here are a couple more images from that evening
