Very disappointing trip tonight...one of those times when it seemed like whatever could go wrong, did go wrong. I made good preparations, set all the camera settings well ahead of time, and still managed to end up with the wrong ISO and Aperture settings It occurred to me driving back home that I had taken the camera with the FDn 400 on it, changed the settings to make some bird shots in afternoon sunlight, put it back in the case and never gave it a second thought. I also tried to make my debut shooting moonscape type shots ...obviously didn't know what I was doing, learned I had the wrong focal length lens, and didn't get a single keeper. I did keep this sorry dark shot...a low sky shot with the 400mm to serve as a strong reminder to pay better attention on my next attempt. I had also decided to use a stronger, heavier neck strap tonight, left it hanging on the camera on the tripod, and without realizing it the light breeze was swaying it just enough to cause vibration/movement and 3/4 of the shots were worse than this one...had to be culled right into the trash can on the first pass.
