 Messier 104 - The Sombrero Galaxy

The Sombrero Galaxy is an unbarred spiral galaxy in the constellation Virgo, 28 million light-years from Earth. 

Andromeda Galaxy

Also known as Messier 341, M31 or NGC 224, Andromeda is  spiral galaxy approximately, 2.5 million light-years from Earth. With an apparent magnitude of 3.4, the Andromeda Galaxy is visible to the naked eye on moonless nights even when viewed from areas with moderate light pollution.

The Witch's Broom

More commonly known as the Veil Nebula this is a cloud of heated and ionized gas and dust in the constellation Cygnus. It constitutes the visible portions of the Cygnus Loop(radio source W78, or Sharpless 103), a large but relatively faint supernova remnant. The source supernova exploded some 5,000 to 8,000 years ago, and the remnants have since expanded to cover an area roughly 3 degrees in diameter (about 6 times the diameter, or 36 times the area, of the full moon). The distance to the nebula is estimated to be 1,470light-years.

Welcome to the Preseli Astronomy Group

The Preseli Astronomy Group offers a warm welcome to anyone with an interest in astronomy. Whether you are an experienced observer, a complete novice or you enjoy reading about astronomy, or watching astronomy programs on TV the Preseli Astronomy Group offers you a warm welcome.

You do not need to own a telescope or binoculars, the group has several for you to have a hands on try before you invest any money in purchasing equipment. Experienced members are also on hand with their equipment and are only too willing to impart their advice.

Meetings are held at 7pm on the first Tuesday of each month (except August) at Letterston Memorial Hall. The usual format is 'What's up' ( the sky this month) followed by a Lecture (see "Events" link for details) and Observation. We also have regular viewing sessions, weather permitting. Novices are especially welcome to come along and discuss any query about viewing and equipment.

There is no membership fee, all we ask is for a small donation to cover the cost of hall-hire and refreshments. So if you're interested come along to one of our events or email us. Alternatively sign up to our forum and introduce yourself.
