Just a pretty picture of the Star Arcturus in the constellation Boötes. Bizibilder took this first last night as it is a very bright star and he could use it to focus his camera and telescope. The “cross” is due to the design of the telescope used (called a diffraction pattern). Some folk think they look pretty others hate them! Bizibilder, as always, prefers to sit firmly on the fence!!

Bizibilder is quite proud of his first DSO picture. It is of the star cluster known as “The Great Globular Cluster” or M13 (Messier’s catalogue number 13)in the constellation of Hercules. It is a cluster of thousands of stars and is about 145 light years in diameter and is about 25,100 light years away. It can be seen with the naked eye (just!) or binoculars will show it easily as a smudge. This was taken with an 8” (200mm) diameter telescope.
(Eight minutes exposure, processed a little to eliminate light pollution.)
I’ve added a close up of the “core”:

This is what Bizibilder has been trying to achieve with all his building and buying of Astronomical stuff! Full Moon (when you can see the visible disc fully illuminated) was at around 6 o’clock this evening. This photo was taken at around 10.30. There is not much crater detail as, if you were on the Moon, the Sun would be directly overhead (ie “Moon Noon”) and therefore there are few shadows.
For Techies: 7” f/15 Telescope, prime focus. Canon 1000D 1/250th sec ISO 1600. Contrast and brightness reduced (due to overexposure as the ISO setting is too high!!)(Excited Bizibilder!)

Or how Bizibilder found out JUST HOW DIFFICULT it is to take pictures of wildlife!!
