What is a dielectric diagonal

What's the difference between a normal diagonal and a dielectric diagonal? I know that the word, dielectric, is more or less a synonym for electrical insulator, a material with a low (compared with that of a metal) electrical conductivity. But how does that relate to an astronomical instrument such ...

Star trails

The light pollution in my area in STAGGERING! I live in North West London, but I thought I'd give star trail photography a go. I used my wife's new 70-300 Canon IS USM lens attached to her Canon 350D SLR camera to take these photos. Even after processing in Photoshop the light pollution is very evid...

Ah - joy! After two years of slog at UCL attending Astronomy classes twice a week during evenings, doing home work, visiting the North London Observatory to work on lab scripts, observe and astro-image - I finally graduated last night and received my Undergraduate Diploma in Astronomy!

David, As magazines go, I find that Sky & Telescope has the right level of depth in their articles. I also like the writing style adopted in Sky & Telescope. I find it a pleasure reading the magazine. There is a new magazine out in the UK called Practical Astronomer. I was curious about it after I g...

Independent Newspaper 26/07/2006

Heads up all you space brains! There's a double page spread in today's Indi, Extra Supplement, page 10/11 which covers some of the big ESA missions coming up including Darwin, Xeus, Dune and others. Nice "what's up in the sky" for August column as well. Odd - a national heavy weight newspaper actual...

Knocking out the street lights

Have tried knocking out the street light with my green laser pen but it never works... where is the sensor on the light? On top of the reflector? It works a treat on the neighbours insecurity flood light though. That's a top bonus for when I'm observing in the back garden. Even funnier is using one ...

HippyChippy,

I don't know really. Probably best to ask Google or the people who wrote the overlay. If it were me, however, I'd use use the overlay as a guide and use my common sense :-P

Google Earth European Light Pollution overlay

Here's one all of us will like. If you own a PC or Mac that's powerful enough to run Google Earth then download the European Light Pollution Overlayfor it. It's quite good.

Processed images

Hi Dave, That was quite an interesting experiment! I have done this on Yahoo messenger before and it worked out really well but this was the first time I tried relaying images from my telescope in realtime over Skype. It worked out quite well I thought. It's a shame the Philips Toucam doesn't show a...
