Seemed like a good target to try out the new 800/5.6 on. I focused manually on a fairly bright star with the viewfinder, and fired off a few high speed bursts at various shutter speeds while trying to follow the ISS so was not sure if the result would be good. I was surprised that a high percentage came out quite sharp.
