I had a bunch of setups and somehow things didn't all work properly.
1) ecipse maestro + ioptron skytracker + canon 6d w/180mm f/2.8 lens
I used a compass to polar align, but somehow the sun would drift off the field of view after about 30 minutes...that was a bit annoying for trying to shoot over 2.5 hours
2) Mak C90 + DIY cardboard filter cell + dwarfstar mount + sony a7s at prime focus + 9x50 right angle finder (with filters)
It was quite difficult to find the sun in the 9x50 (and pretty much impossible in the C90). I had to swing it around randomly and get lucky. I had to move the mount every few minutes or else it would drift off the field of view
When I removed the cardboard filter cell from the C90, the Dwarfstar's balance changed while I wasn't watching and within a few seconds C90 was pointing nearly overhead. I tried to find the eclipsed sun and could not.
Finally the C90 had some weird halo like reflections in my A7S photos when the filter was off.
3) iPhone video camera. I tried to record video and it gobbled up my 2GB of remaining storage in just 10 minutes (I started maybe 15 minutes before totality). I deleted the file and tried to record more but I forgot to empty the trash folder on iPhone so I missed a video of totality.
I expected 2GB of storage to be sufficient for at least 20 minutes of video. It was not.
4) Point and shoot camera for backup.
For some reason the battery was dead during totality. I have no idea why.
