Planetary trio

We went up on to the moors above our house last night to try to view three of our partner planets at the same time. Venus,Jupiter and Mercury are all visible low in the North West just after the sun sets.

There was low cloud on the horizon as the Sun set but it was clearing as we watched. Eventually with binoculars (only used after the sun had gone!) we spotted Venus and as the twilight deepened Jupiter and then Mercury. 

Eventually they were all visible with the naked eye until they one by one sank below the hillside. 

The three planets formed a triangle which just fitted into the field of view of the binoculars so just about 2.5 degrees across.

The picture is a stack of ten exposures taken just before Venus disappeared into the cloud, aligned, processed and annotated using Nebulosity and Lightroom.
