  1. Hi Dave I've completed S197 too are you working towards a specific qualification? I'm also doing SXR208 in April & I can't wait! How are you finding S282 so far?
  2. Hi All, Before I purchase a telescope I'd like to learn as many of the constellations as possible. The last few nights I've been out for walks in the countryside armed with an iphone app & binos and I've identified like 7 constellations. There are a few others that I can't quite identify all the stars in but I can tell the region. It definitely adds to the magic when I know what I'm looking at. Anyway does anyone have any tips to share on the best ways to learn the constellations - any books/software/apps/methods etc.? BTW the iphone app i'm using is http://itunes.apple.com/us/app/planets/
  3. Hi Adrian I'm not an expert by any stretch of the imagination but I'll have a bash at answering your questions (I'll refer to a single neutron star rather than a pulsar): 1. It would look like a flattened sphere (much like Jupiter, Saturn etc.) due to its rotation rather than length contraction. The effect would be much more pronounced though as it's mass & therefore gravity is much greater. 2. It is rotating 700 times per second as viewed in our reference frame on Earth. If you were to stand close to the neutron star you'd observe it to be rotating slower but a 'second' would also be long
  4. Hi all, I'm looking for some advice for my 1st telescope purchase. I live within walking distance of some great observing sites & as I don't drive (yet) I need something as portable as possible. I'm not sure if I'm allowed to link to other sites but I've had a search around and found a few models that are sold as travel scopes, I'm wondering if any of these are worthwhile? Or is it better just to look at small telescopes and buy a backpack to transport them? My budget is up to around £200. Finally I'd appreciate any advice on minimising wear & tear as I'm going to be lugging it about
  5. Hi All, I'm pretty much a total beginner, I've joined up to learn as much as I can and hopefully be able to contribute one day! I've completed an introductory short course in cosmology through the Open Uni & I've just begun a level 2 Astronomy course but I don't have much experience of observing, though I hope to rectify that over the coming months Alan
