12113 Rough HDR composite of the solar corona! How do you make your HDR composite?  I have two exposures, scaled and rotated to match, and I found a description on how to do it in gimp, but it was a quite manual process more aimed at fixing a dark landscape and a bright sky. GIMP, using layer masks...

12192 And the vibration of the mirror flipping adds fuzziness. Does your camera not have a mirror lockup feature? If it does, I recommend combining that with a 2 second timer - when you press the shutter, the mirror flips open, and the timer starts. 2 seconds is enough to allow almost all of the vi...

12160 What was the focal length used? 250mm, of course. 12171 I've been hearing lots of reports about people crying and being overwhelmed with emotions during totality. I was a bit surprised by how little the totality affected me emotionally. It was cool and all, but... I don't know, I guess since ...
