300mm full manual off a tripod. Basic Moon photos are always tough, since the Moon is MOVING, and it is so bright compared to the background. Eclipse photos add the twist that the exposure changes drastically during the event, so you are constantly shooting brackets and evaluating. I used from ISO 100 to 3200, shutter from 1/125th to 2.25 second, and f/4.0 to f/5.6. I was interested in capturing some sharp stars and I found that with THIS lens on a non-tracking mount, *1* second was as long as I could go before the stars became little “-” marks… Also, by 10:15 MST, the darn moon was approximately 60 degrees above the horizon, so it was harder and harder to see the viewfinder and manage the camera. I ran out of head adjustment, and started shortening a tripod leg!
