Moon Phase Names

Hi all, As I'm sure most of you know, the phase of a moon when we see it as a D shape is known in astronomical terms as a quarter moon. (Either waxing or waning). It is presumably named 'quarter moon' because that's the amount of the moons surface you can see. However, this is also commonly called a...

Thanks for the advice.
You've certainly highlighted how dangerous these things can be, almost put me off buying one now. I'll see how much they cost to decide.

Can't get none.

I'm very dissapointed that I've never seen any astronomy magazine in the London Cannon Street station branch of W.H. Smiths.
I rely on subscriptions, but would be glad of something interesting to read on the journey home.
Hopefully this new BBC incarnation will be on the shelves.

Proposal to eliminate Light Pollution

As a regular night time observer living within 20 miles of the British capital, I am constantly shocked at how hard it is too see anything beyond a 3rd- 4th magnitude star on some nights. I have noticed several campaigns to reduce the effects of light pollution in our skies, and wholeheartedly suppo...

Laser Pointer Advice

He everyone, I would like to buy a laser pointer to help point out interesting objects and constellations to my kids. I've heard that the green ones are best for this, but get confused at all the milliwatt descriptions and am worried about all the bad press laser pointers get for being ' terrorist w...

Thanks very much for the great replies. That's exactly how I did imagine the planets and was why I couldn't figure out why I'd never seen them in different phases with the unaided eye. I spent quite a bit of time viewing mars through a telescope back in late 2003/04 but never noticed any signs of th...

Why do planets shine?

Can anyone explain why planets appear to shine all over. That is, the side of the planet that is facing earth appears to give off an equal light. When actually the Sun, whose reflections cause the planet to shine, can only shine on half of the planet, and not necessarily the half we are viewing. The...

This may sound silly, and I've got no idea if it works or not, but have you tried making some long paper/card tubes to stick on the end of your binoculars? If you take 2 pieces of black A4 card and roll them into tubes, once you stick these on the end of your bins they should cut out the street ligh...

If only it was as easy as those good old days when all you had to do was tie a bit of string between two old tin cans :wink: Modern technology can be a headache, but when you actually consider how complex a task it is performing, it's not surprising that occasionally it doesn't do what it should.

Thanks for the suggestions guys. I like the idea of getting the sheep back into the fold, it fits in very well with the rural theme of the book in question. Even though Venus would never appear in the sky at the same time every night, making it a naff signal for when to herd the sheep, it would be s...

What's a folding star?

Has anyone ever heard the term 'folding star' before? It's an old fashioned saying, but I can't figure out what it might be describing. Perhaps a planet, perhaps a comet or variable star. I came accross it in Thomas Hardy's book 'The Woodlanders', to quote ....'to meet him under the declining light ...

Many thanks to Brian & everyone else for the tips on the Toucams.
Looks like it's not as cheap as I first imagined to set up, but still a great way to capture images.
Wishing you all a very happy New Year

Managed to see this comet for the first time last night. I don't think the bright moon helped viewing conditions much, but it still looked pretty neat. Couldn't see any signs of a tail, but will persevere. Found a handy website for finding it's exact location which may be of use to some of you..... ...

Hi Joe, Yes it does have a back, which is well padded, and goes up high enough to support my neck when I nod off to sleep. The back doesn't get used much while I'm at my scope, as I'm normally leaning over the eyepiece, but I do tilt it forward to try and stop me slouching too much. If I extend the ...

Hey, if you are only going to use it in the dark, who cares what it looks like? :lol:

I've also got a Celestron scope, does anyone know how much one of those adapters for the toucam would cost?

There has been so much talk about webcams lately I'm really intrigued by them.
