I have been interested in astronomy and space exploration since childhood. I remember being taken out to the playground at primary school to watch an eclipse of the sun, and the impression it made on me.

I gave my first lectures on space whilst at school in 1969. From 1973 to 1975 I was chairman of the Astronomical Society at what is now the University of Hertfordshire. During this period I gave about 20 lectures on astronomy and space, and also devised and presented a course for three local scout groups for their astronomy badge.

I was a member of the Astronomical Society of Haringey from 1973 to 1977, before working for a time in Utah where I joined the Salt Lake Astronomical Society and gave presentations on astronomy at their meetings. I was interviewed on KSXX radio about my astronomy and space activities.

In 1999 I observed the most amazing astronomical spectacle - a total solar eclipse - not from Cornwall, but from Ramnicu-Vulcea in Romania. I gave two presentations on eclipses and space exploration for the large group which had flown out from England. I was also interviewed on Romanian TV, who broadcast my video footage of the eclipse.

During August and September 2003, I held a public exhibition on astronomy at Welwyn Garden City Library, covering National Astronomy Week and the close approach of Mars.

I have been an active member of LDAS since March 2003, and was elected chairman in 2004. I have assisted in public displays and other events such as the Transit of Venus, when we welcomed school groups and members of the public to our observatory. I also gave two live radio interviews about the Transit and I have given several presentations to the society and written articles for their newsletter.

I have done a number of radio interviews about the society with BBC 3 Counties Radio, Hertbeat FM, and Chiltern FM.

In 2006 I led a group of 10 astronomers on a trip to see the total eclipse in Turkey.

I am now a freelance presenter on Astronomy and Space Exploration. I give public presentations on space across the UK and abroad and I present workshops on astronomy and space for schools at both primary and secondary level.

I began my astronomy activities watching the Moon through my father's binoculars, then with a small telescope, but my major interest is in space exploration. I presented an 8-part evening course on the subject at the University of Hertfordshire during Autumn 2004.

In recent years I have returned to astronomy more and have a Meade ETX-90EC scope with a range of eyepieces, solar filter and other accessories. I have taken some 35mm stills through the scope and some very pleasing video sequences of sunspots, the Moon, Mars, Jupiter and Saturn. I took some pictures of the Transit of Venus with a digital camera, and this is an area I would like to explore further.

My other interests include films and books - especially science fiction - photography and genealogy (I have a family tree with several hundred entries on it).

I am now also an international author, having written a book about Apollo 11 which has been published in the UK, the USA, Australia and other places. It's called "One Small Step" and commemorates the first men on the Moon. It is presented as the scrapbook of a young space enthusiast whose grandfather worked in Mission Control during the flight of Apollo 11.

I also write the Space Exploration column in "Popular Astronomy" - the magazine of the Society for Popular Astronomy.
