As I had always feared, the screw on the bayonet mount was not tightened enough and my babied Mark V's crashed onto asphalt. The damage is mechanical with dents and heavy miscollimation but the optics look intact. I contacted AP and they were good enough to contact Baader on my behalf but the cost is heavy: $735 + both ways shipping which I expect will bring it north of $900. Since Denis says he doesn't accept repair orders any more because of customs issues and given that Mark Vs sell for $1200-$1400 used, I'm finding it hard to justify sending them to Baader, and that too for an unspecified amount of time. My backup plan is to spend around $500 and get the Maxbright 2. But that will leave me with the conundrum of what to do with the damaged BV.
