Having recently bought a 400mm f/2.8 lens, I have been somewhat keen to use it.
I bought it to photograph wildlife during our next African safari, but for the lack of any local leopards or lions, I decided to use this lens for the next best subject: the moon.
Here, on 6 September, 2014, the moon is in Waxing Gibbous phase.
I headed outside earlier this evening to photograph the moon, which was a challenge given the heavy cloud cover that was blowing over.
During one of a few short windows of opportunity, I captured this frame.
Ignore the focal length of 800mm; I actually shot this at 1,120mm as a result of having stacked both my 1.4x and 2x tele-converters; but when stacking more than one tele-converter, the focal length and aperture are not transmitted to the camera, so it appears that I used only my 2x tele-converter.
