‘I enjoyed the scientific work, especially solving problems and understanding the physics of the stars, so doing something like this is a kind of motivation for other people to become interested in astronomy and until you study physics and astronomy, you don’t really know what is going on in the stars and you don’t see what professional astronomers are interested in. There are many things happening in our own galaxy and in our own solar system and of course with the space age we know a lot more now about planets and asteroids and many things. So even quite nearby objects turned out to be more interesting than people realised in the past. I studied the heat radiation from stars, with infra-red light. Usually stars that are forming or stars that are dying have a lot of dust around them and this shows up very strongly in the infra-red, so I studied basically variable stars that show up brightly in the infra-red and I studied certain types of galaxies which have active centers, the nuclei we call them - and quasars. So you think of stars, but dust and gas are also very important parts of the galaxies in the sky.’

CHRIS FORDER'S TELESCOPE, CEDERBERG ASTRONOMICAL OBSERVATORY, WESTERN CAPE

'We got music going - we try to keep it to calm music, so that we are not too excited. If you get too excited then things start going wrong and you start doing stupid things. You must just keep calm the whole time while you are imaging. After all, the stars will wait - if you don’t get them tonight, you can get them tomorrow night. Time is nothing to them, time is everything to us. '

'If you consider there are between 10 and 20 times as many galaxies outside ours as there are stars in our galaxy - and we have maybe 200 billion stars, so multiply that between 10 and 20 and that is the number of galaxies, and each of those may have 200 billion starts. So we are pretty insignificant. If you go and look at a piece of sand outside. That is how insignificant we are. We think we are important but we are not.' - Chris Forder. Amateur Telescope builder.

'Are we alone, I don’t know - the thing is we will probably never know. If we find a civilization that can signal to us, we’ve got to be able to signal to them. If they are a 100 light years away we are talking about a 100 years between every communication, and by then the other one may have died out or they may have not reached the communications technology or we may have blown ourselves up enough to have to start all over again. So we will probably not communicate with anyone out there - not in our lifetime. But there is probably someone. We are so proud that we call them aliens - we may be the aliens. Who knows.'

PROJECTION SCREEN, CEDERBERG ASTRONOMICAL OBSERVATORY, CEDERBERG

'We all sat down in this amphitheatre - everyone so excited. Waiting for it to start, and then every now and then a car would arrive in the parking lot and its lights would shine onto the screen and then everyone would freak out a bit. This guy gave a presentation, using like Hubble telescope photographs, each and every photo - incredibly impressive full multicoloured images. This all whilst telling us about the telescopes they themselves have built and that we will be able to see Jupiter with them after the presentation. When we eventually went to look through the telescopes - it was all monochrome tiny little things, no multicolored Hubble stuff. Anyway, it was so great though seeing these old guys, listening to Led Zeppelin, who go up there every two weeks, observing through the night. It’s their thing, it is like playing golf to them'
