A bit about me

 

In used to work for London Underground but have now retired. I have a number of interests both in amateur astronomy, Citizen Science, Astronomical History and passing on some of my knowledge to other people both in astronomical societies and in public lectures. I am also a part time student approaching completing a degree in Astronomy with The University of Central Lancashire.

I am also interested in the opportunities that are now available to Amateur Astronomers through the 'Virtual Observatory', this allows worldwide access to large quantities of astronomical data and allows you to select how to present and analyse it. There should be lots of opportunities there for amateur Astronomers to make discoveries. More details are on the page below.

I enjoy trying to photograph astronomical objects and special events such as transits, conjunctions, eclipses and occultation's. More details on this are on the pages linked below.

I also have an interest in the weather - this started at school and has continued through my sailing days to my present pre-occupation with astronomy. In the Summer I also hunt for Noctilucent Clouds - as they are on the edge of space they are somewhere between weather and astronomy.

I am a member of a number of organizations which are linked below. I also try to support the RNLI having been rescued by them in the past ! I also have an interest in making things - in particular I have always enjoyed Blacksmithing - I think it must be in my genes as I have discovered that both my paternal grandfather and great-grandfather were blacksmiths.
