Visual testing and finder alignment shows a VERY capable system, despite the INTENSE heat shimmer I am looking through at my aim tree. As typical with Vixen, it's either in focus or not - it snaps right to focus with MINIMAL in focus range (SO nice, compared to mushy systems!)
I cleaned the mirror with a VERY soft natural hair blusher brush (new, that I "obtained" from the wife's stash

)attached to a long dowel. Came up as new, no spots. Of course, can't clean the secondary or face of the flattener easily
Tonight SHOULD be good, so images to come
