In July 1054(AD), a bright new star appeared in the constellation of Taurus. We have records from China, Korea and Japan and from some Islamic scholars. The star was visible even in the daytime (if you knew where to look) for about 23 days before gradually fading from view. It was one of the brightest things in the night sky, but does not seem to have been recorded in Europe.

This is probably the most spectacular nebula (cloud of gas and dust) in the night sky, but is too far south to be visible from the UK. Like the great Orion nebula (visible from here in the winter), this is easily visible with the naked eye, and glorious in any telescope. The Great Carina Nebula is a complex area of glowing gas and dark dust aprroximately 8,000 light years away from us in the direction of the constellation Carina.

The constellation of Orion dominates winter skies in the Northern Hemisphere. The shape of Orion, the hunter, and the three stars of Orion’s belt, are familiar to anyone who looks around the night sky, but the naked eye has to track along Orion’s sword (hanging from the belt from the Northern Hemisphere) to have any hint of the glories this constellation reveals to any telescope. The faint, small, fuzzy patch is the famous Orion nebula, but there are many extraordinary nebulae here.

Not a large spider, but an astonishing area of the night sky. The image shows the area in the constellation Dorado (the Dolphin fish or Swordfish), around the Tarantula Nebula, a huge area of gas and dust where stars are being formed, which is in the Large Magellanic Cloud, a nearby galaxy outside our Milky Way, and closely associated with it. There are a lot of firsts for me in this image.

I am very pleased with my first image from iTelescope of the famous double cluster in Perseus. I have not yet managed to unpack my telescope and CCD camera since we moved here. On the rare occasions that I have had time to think about practical astronomy, the weather has not been helpful. Although the night sky here is much better than it was in our old house, it is not good.
