Comet C/2013 US10 (Catalina)

Just managed to catch Comet C/2013 US10 (Catalina) last night before it gets ejected from the solar system forever.
























The comet is 68 million miles away travelling at 132,000 miles an hour and was  near the star Alkaid in Ursa Major.

M108 Galaxy & The Owl Nebula M97

Two amazing deep sky objects in one image taken in the Constellation of Ursa Major.
TOP LEFT - M108 (NGC3556) is a barred spiral galaxy discovered in 1781. It is 46 million light years away and has a mass 125 billion times that of the Sun with a diameter of 100,000 light years. Its often called the Surfboard Galaxy as from Earth its seen edge on.
BOTTOM RIGHT - M97 (NGC3587) is a Planetary Nebula about 8000 years old and also discovered in 1781. Often called the Owl Nebula its about 2600 light years away and if you look closely two owl eyes can be seen, The centre star in this nebula is a white dwarf star.

NGC 2903 Barred Galaxy

NGC 2903 is a beautiful, faint barred spiral galaxy similar to our own Milky Way Galaxy but about half the size in the constellation of Leo. NGC 2905 is a bright star cloud within this galaxy.
Its about 25 million light-years away.
That sounds a long way away and it is.

If you could travel at 671 million miles per hour ( the speed of light) it would take 25 million years to get to this Galaxy which is about 80,000 light years across.
