  1. I've got SkyVoyager and Star Walk on my iPhone, and Starmap Pro on my iPad. I've found Starmap very useful for planning when planets and celestial bodies are visible (great for the moons of Jupiter too), but it strikes me as a bit too complex for field use. Star Walk is fabulous for orientating yourself in the (light polluted) night sky. Haven't played with SkyVoyager much, got it when they were giving it away for free during the moon landing celebrations last year. Thanks for the book recommendation.
  2. Thanks for the replies. I've seen the Turn Left at Orion book, but was never sure how suitable it was for use with binoculars. I'll have a another look. The IFAS PDF in the binoculars links looks very good, I think that combined with one of the virtual star maps apps on my iPhone will be enough to get me started. Thanks.
  3. Hello all, I'm fortunate enough to own a rather nice pair of Nikon HGL 8x42 binoculars which I have been mainly using for terrestrial observing and a bit of (very) light astro. At some point in the future I'm planning on buying a telescope, but figured I'd get started with the binoculars I already own, to that end, can anyone recommend a book or a website that is geared up for someone with low power binoculars? We're planning on going on holiday somewhere dark and secluded at some point in the next six weeks, I've also managed to track down a tripod adaptor (why is that fancy binoculars never have a tripod screw?). I have a good carbon fibre camera tripod and ball head, I'm guessing that using it will be hard work on my neck, but that it should be fine for an initial foray?
  4. I think the eye relief is where you eye needs to be for the optimum view. So if you have an eyepiece with 20mm of relief then you want the front of your eyeball to be 20mm away regardless.
  5. For eyeglasses the main thing is the eye relief of the eyepiece, about 20mm is enough, though it depends a bit on the thickness and geometry of your glasses (i.e how far away from your eyeballs they are). If you can try using an eyepiece somewhere / somehow with a known eye relief that should give you a good frame of reference. Also, in case you don't know, if you have no astigmatism, you don't need to wear your glasses if you don't want to, you can adjust the focus of the telescope to compensate for your eyesight. If you do have astigmatism, then TeleVue make correction lenses that can be attached to some of their eyepieces, Unfortunately TeleVue stuff is quite expensive, but it might be worth bearing in mind for the future.
  6. Does anyone here use Televue Dioptrix correction lenses? Do you find they make a big difference? I've got -1.00 astigmatism in right eye (-1.50 in my left), and I'm wondering if sticking to eyepieces that accept a Dioptrix might be a good idea? (Rather annoyingly that seems to be an expensive set to choose from...)
  7. Is the WO TMB 80/480 still being made? I have to say I get thoroughly confused by the comings and goings of various WO designs.
