It's a clear #night and #Jupiter and #Venus are bright in the #western #sky and getting closer together in their apparent positions. This is a #photograph of the pair with a 1.6 s exposure. It is also difficult to get a sharp #focus manually as autofocus doesn't really work with objects at infinity and yet effectively points of light. This taken with a 400 mm #telephoto #lens.

Also with long exposures and a heavy lens, even a the tiniest #vibration on the tripod can blur the image, even with the sharpest focus. Here's the same image but cropping around Jupiter. You can see its four biggest satellites, (left to right: #Europa, #Io, #Ganymede and #Callisto, information courtesy of #Stellarium)
