About the Site

 I try to log my observing and related activities in a regular blog - sometimes there will be a delay but I usually catch up. An index of all my blogs is on the main menu at the top of the page with daily, weekly or monthly views. My Twitter feed is below. I am also interested in photograping wildlife when I can and there is a menu option above to look at some of my images. I try to keep the news feeds from relevant astronomical sources up to date and you will need to scroll down to find these.

The Celestron 14 is mounted on a Paramount ME that I have been using for about 10 years now - you can see that it is mounted on a tripod so is a portable set up. I still manage to transport it on my own and set it all up even though I have just turned 70! It will run for hours centering galaxies in the 12 minute field even when tripod mounted.

The Planet Uranus

I accidentally rediscovered the planet Uranus in the early hours of this morning.  Having recently acquired a 14 inch OTA to replace its 12 inch predecessor and being used to pointing and clicking to go to any object I realised how difficult it was to find anything at all with the 14" and a non-aligned finder! Having failed to get any known bright stars in the 26 mm eyepiece I tried to locate Jupiter which was shining like a beacon in the eastern sky. Still no luck - I could not find it! I slowly "panned" back and forth in what I thought was its vicinity by sighting down the tube and spotted a definite disk in the viewfinder. Too faint for Jupiter but it struck me that this must be Uranus. I checked the chart and there it was - not far from Jupiter. I centred it, changed to a  9 mm cross hair eyepiece and "synched" it to "The Sky" software and made it the first mapping point in a new T-Point model. I now asked the telescope to slew to Jupiter and there it was at the bottom of the eyepiece field. I centred it and synched it and aligned the finder to the OTA. From now on everything became much simpler and after half a dozen slews to bright stars and mapping them I was getting fairly well centred objects in the 9 mm eyepiece. With a focal length of 3910 mm that corresponds to a magnification of X434. Replacing the eyepiece with the SBIG camera put objects into the field of view with each slew.
