Has anyone talked about a meetup for the eclipse?
Here's a pic I took of the full moon last month:
I find that the full moon often looks flat because of the front lighting. October last year I took a shot of the moon one day past full and the slight amount of side lighting accentuated the features more:
Years ago, I picked up the tip that correct exposure for the full moon is 1/125 @ f/8 @ ISO 100. I've always used this exposure setting or one stop more. I've come to prefer f/11 over f/8 because it gives more contrast. Both of the photos above were shot at 1/125 @ f/11 @ ISO 100.
Something you want to keep in mind about the eclipse, though, is the light will be dropping off dramatically once totality has begun, so you'll want to adjust ISO/aperture/shutter speeds accordingly. You can't let the shutter speeds get too slow, though, or else you'll be suffering from the moon's motion-induced blur.
A few more tips --
I'd say just about the absolute minimum focal length for this is 300mm if you want to record any significant level of detail. The above pics were taken with a 650mm and a 500mm respectively.
A stout tripod is a must.
Either a remote release or a self timer with at least 10 seconds duration is required. You need to let all vibrations caused by focusing and touching the camera to trip the self timer to have settled down before the shutter fires.
If you have a long auto-focus telephoto, then great -- you're probably set. But if you're like me and you're using an old T-mount manual focus lens, well in that case, I strongly recommend some type of focusing aid. You cannot rely on the infinity mark on your lens -- it won't be accurate enough. If your DSLR has Live View, use it to confirm focus (I'd recommend you do this even if you're using an AF tele). If you don't have LV, use some sort of viewfinder magnification eyepiece accessory. If you don't, focus will be hit-or-miss, most likely miss.
