| well...the clouds never blew off Friday night, so no practice that night. then the moon rose already eclipsed (sp?) saturday. i tried shooting a little, but nothing turned out well...too much wind and clouds. i'm hoping the next eclipse is in the summer or sometime when it isn't snowing here. oh well. |

It doesn't make a difference how close or far you are from the subject it's the amount of zoom used that dictates the amount of blur due to camera shake. The rule of thumb is to choose a shutter speed that is faster than the lens length in mm (35mm equivalent). That is for 50mm 1/50 sec shutter speed, 200mm 1/200 sec. in this case faster than 1/306 sec. is required so 1/320 sec. should be OK, as this is on the limit you'd still want to hold it very steady of course. |
This is true of something that is here on the ground. But when you are talking about something that is hundreds of THOUSANDS of miles away, the minutest little camera shudder will result in a soft shot.

This is a shot I got the night before the eclipse while I was taking "setup" shots (and then we were overcast the night of the eclipse).
ISO 400, 1/640s @ f/5.6, 300mm (450mm eff.)

It is a 100% crop w/ mild adjustments in ACR. I got some distortion at the bottom edge of the moon and I'm not sure if that is from heat off the houses across the street or what (any ideas?).
