Safety: Please remember to never observe the Sun without proper eye protection. Solar glasses are needed to observe naked eye and proper objective mounted filters or projection should be used to observe it in binoculars or telescope.
I had the privilege of visiting Snowdonia this summer for a family camp in a beautiful river valley near Maentwrog. During the evenings I managed a bit of stargazing before moonrise and captured a few bright constellations over the Welsh hills.

I also captured a lovely close pairing between the Moon and the planet Jupiter.

The highlight, however, was witnessing a beautiful partial eclipse of the Moon on Tuesday evening at around 11pm.
I took these pictures and a short video using my smartphone anchored to a simple pair of 8×40 binoculars (mounted for stability). The eclipse was already underway when the Moon rose into view and continued until well after midnight.
Look out for a spectacular total lunar eclipse next Monday 21st January, when the full Moon will turn blood red in the sky. I’ve put together a video guide below with details of the timings for the full event at northern GMT latitudes.
You’ll have to get up early in the morning on the 21st to witness totality, with the best observing times spanning 4.42am – 5.45am. Set your alarms!
This Friday (the 27th of July) the Moon will rise into view in the south east around 9.30pm with an unusual red colour. This is due to a rare phenomena known as total lunar eclipse – when the Earth sits directly between the Moon and the Sun.
But why doesn’t the Moon darken if its light supply is cut off by the Earth, and why will it turn a red colour?
The best way to think about this is to imagine yourself standing on the surface of the Moon as the Earth slowly passes in front of the Sun.
As the disc of the Earth begins to occult the Sun it will start to darken until finally the whole of the Earth sits in front of the Sun. But as this takes place something amazing happens. The Earth’s atmosphere refracts the sunlight into an intense circle of vibrant sunset. It’s this ring of fire around the Earth that illuminates the Moon during totality, giving it an eerie red colour.
This far north between 9.30pm and 10.30pm it’ll still be pretty bright outside but the colour change should still be obvious to see. As the evening progresses the eclipse will become partial and will be almost over by midnight.
Totality for this lunar eclipse will be 103 minutes making it the longest in this century. As my animation below shows we won’t be able to witness the start of this eclipse, only its middle and end.
