[QUOTE="Bob Blaylock, post: 370128, member: 16749"] I did some test shots of the sun, to get some idea what I was up against. As I feared, even with my Vivitar stopped all the way down, and the shutter speed at 1/4000″, the sun's too bright. Live View mode, I noticed afterward, imposes a minimum of 200 on the ISO rather than the 100 I thought I had set for. There was some hazy cloud cover, not enough to conceal the sun. Some of the clouds around the sun are exposed just about right,but the sun itself is completely washed out.

[ATTACH alt="DSC_4316.jpg"]119891[/ATTACH] A few hours ago, I had this bit of inspiration: [ATTACH alt="CSC_4335.jpg"]119892[/ATTACH] A cardboard disk with a pinhole, and a bit of foam rubber to hold it in place. Will it be enough? I'll have to wait 'til the sun is up and out to test it, but here's a test I did using a luminaire in my home, same ISO, same shutter speed, one shot at ƒ22 on the lens' built-in aperture, and the other using this pinhole. [ATTACH alt="DSC_4329.jpg"]119893[/ATTACH] [ATTACH alt="DSC_4330.jpg"]119894[/ATTACH] This may all be for naught. It looks like there's a good chance that it will be cloudy and rainy where I am tomorrow, denying me any view of the eclipse. [/QUOTE]
