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 Sky this morning - 17th November 2014

6 a.m. and going out with my 8 X 30 binoculars another glittering sky dominated by Orion to the South West with Jupiter very bright at magnitude -2.2. After a minute or so I realise that in fact there is a glow to the sky and spot the Moon at altitude 35 degrees towards the East. I automatically look at the Great Nebula in Orion through my binoculars first - a sort of ritual now - and particularly notice the pairs of stars sitting in a line at different angles to that line.

I didn't see this - I used a remote telescope to take this image

 or this - taken with my Sony camera and telephoto lens at 400mm

but that's getting closer to the visual impression - without the colour of course.

It certainly wasn't like this - taken with the Sony Alpha at 500mm.


I used the same camera and lens to quickly snap the Moon this morning
