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)

Morgens um 10 vor Acht ist die Welt noch in Ordnung - #Mond und #Antares leiten einen zur Arbeit (rechts liegen lassen!) und die #Sonne lauert verheißungsvoll hinter dem Horizont :-)

A huit heures moins dix du matin, le monde est encore en ordre - la #Lune et #Antarès vous guident vers votre travail (laisser à droite !) et le #Soleil vous guette, plein de promesses, derrière l'horizon :-)

In the morning at 10 to eight, all is still right with the world - #Moon and #Antares guide you to work (leave it to the right!) and the #Sun lurks auspiciously behind the horizon :-)

A #terrestrial demonstration of why it's just about impossible to see the #Moon's surface and #stars simultaneously. Tonight the Moon and #Jupiter (a wandering star or #planet) are in #conjunction -- well just about. And here are two images taken with two different #exposure time.

The first is with a #ShutterSpeed of 1/6 s. The lit part of the Moon is a white featureless blob but, because it's a #misty #night, there's a wonderful #ice #halo which shows #colours from the #VisibleSpectrum. You can see Jupiter directly above.

Next, with a shutter speed of 1/100 s, the #surface of the Moon shows much more contrast but you can barely see Jupiter. Also, the #fog is also invisible.
