Are those shots happening live? What is your set-up, looks really really interesting! I tried to watch the transit of Venus in 2012. It remember it was very early in the morning in Norway, maybe 5 or 6 am. We had clouds. My daughter and I came home and watched a live feed from an observatory instead.
Oh yeah, those were taken on my iPhone over the course of about 30 minutes to an hour between the two shots. We had excellent timing for the event (~1700 local time), and only a few little cumulus clouds to contend with. We had a tripod-mounted Cassegrain-Schmidt (I think) telescope projecting the solar disk up through the eyepiece onto a slab of white poster board. There was a nice little crowd of people in the parking lot where we were doing this, right outside of a couple of office buildings we all work in. Also, a tinted filter on the 'scope so as not to melt the optics. I got lucky on that one, but I've had to chase a lunar eclipse up into the hills west of town. We punched through the low cloud deck just before totality. No pics on that one because cameraphone + moon photography of any kind = bad results.
