I've learned a couple of things while taking pictures of the sun in order to get ready for this eclipse:
I look through the view finder rather than the looking at the monitor/live view. For me, I find I can get better focused pictures of the sun this way.
I also open up a patio umbrella similar to this:
patio umbrella
I put that umbrella to just above my height with the camera on my tripod and I attach a dark towel, 3' wide (or so) to hang down from the umbrella and have that towel laying over the
top of my camera lens. That towel helps keep the sun out of the area my camera is at so I see my camera settings better, that plus it helps when I'm looking through the view finder to take the pictures.
I did use a small diameter bungee cord once to bungee it around the camera when the wind was blowing to help keep it from getting in front of the lens and partially covering it at times.
I'm hoping all this preparation comes in handy the day and times of when the eclipse happens:
Start of partial eclipse (C1): 2:15:03 pm
Start of total eclipse (C2): 3:27:47 pm
Maximum eclipse (MAX/Totality): 3:28:30 pm
End of total eclipse (C3): 3:29:12 pm
End of partial eclipse (C4): 4:37:56 pm
