Tested my custom solar filter adapter outside. Before the tornadoes arrive.
Ran into an interference issue but I was using the tripod wrong: using the tilt axis for elevation. When I remounted the hex plate, I was able to mount the filter.
Aimed at the Sun and turned on Live View. Ahoy!
Focusing will be a challenge, I realised. But I was intrigued to see the autofocus turn the whole adapter box! Wow. Wondered if the converse would work!? Turned off the AF mode and then rotated the box. The focus changed. Ha ha! I was not expecting that.
Canon 40D, 18-55 lens at 55, manually focused, f/5.6, 1/250, ISO 100, daylight WB, RAW, DPP.
