I gave it a try at home. 8SE at 16x w/ f/3.3 and Lenovo using IOTA VC 2.4. The target was faintly visible (I believe) watching live on screen when there was no cirrus over the target, but cirrus moved in before the predicted time and then it was impossible to see the target through the bright sky. I recorded till 5:11:00 UT. However, tracking was lost on the nearby track star just before the predicted event. I will submit the recording to Lucky Star, but the deepening cirrus clouds ruined the key observing period, as seen below.

This one gets a "purple heart" wounded in battle.
