  1. Now up again; UK website but operating out of EU now (explained in their FAQ)
  2. Don't buy, make. Dead simple if you print it out on transparency film (as we discuss in the thread that @StevieDvd mentioned.
  3. I like to think I've been a tad more nuanced than that. ... something along the lines of "if you're going to get a budget (BA1) 15x70, these are possibly the best VFM". I believe them to be better VFM than the equivalent Skymaster, but I have certainly never lauded their optical or mechanical features and try to instil a bit of realism when asked about their qualities. e.g. from
  4. Covered at the top of p8 of the pdf manual.
  5. Hi David, it's been a very long time... Your reticle question is probably best answered with images; you can download a GP manual as a PDF from or, if you prefer it without watermarks, as individual image files from The hour ring is fixed unless you slacken the locking screw above it - you would normally lock it to 0h for polar aligning and slacken it for observing, if you were using it as a setting circle. When you rotate the polar axis, the date ring should rotate with it (i.e. it should be locked to the polar axis.) Is that any use?
  6. Suggestions for how to test in store, see Yes, but it's one of those nasty flexible plastic ones. You can make it usable by aralditing a length of 6mm steel rod into the recess on each side. Or you could buy a proper one for about seven quid.
  7. If you're going for that, you'd be a tenner better off getting the Rev 15x70 from Telescope House. Essentially the same binocular (different livery and marginally better coatings).
  8. Those are not binoculars, but BSOs (*). As such, they might be useful as a "talking point" paperweight, but not much else. * Binocular-Shaped Objects
  9. The UK-available 10x50 equivalent is the Strathspey Waterproof. Assuming that the only substantive difference between the 10x and the 12x is the eyepieces, in general I agree with Ben's evaluation, but would add that it is internally stopped (iris on the entrance to the prism housing) to an effective aperture of about 44mm and that there is a bit of focus "lag" that is due to the waterproofing O-rings on the eyepiece tubes doing their job properly - not "fatal", but I found it takes a bit of getting used to. But, as the others have said, the difference between 10x50 and 12x50 is slight and something with a bit more magnification and aperture may be preferable. One such option is a 20x60; it is substantially different to a 10x50. Decent new ones are out of your budget, but you may be able to get a good used Tento within budget (there's a brief thread on them here) A friend has one and they are pretty sharp and seem well made. They don't have a tripod-mounting bush but a Kaiser clamp will fit.
  10. I didn't try, but I'm pretty sure that I'd not have been able to see it if I hadn't mounted the bino, it was that near the limit of visibility.
  11. Forecast was promising so I legged it up to Hyde Common to see if I could bag Comet 45P. I took the Lunt 16x70 and the Amazon basics {aka Ravelli) tripod and joystick head. There were various "tests" on the way: * I knew that I would have no chance with the comet unless I could easily see Neptune. By 17:15 it was easy with direct vision at the centre of an equilateral triangle that had Mars and a couple of 7th mag stars at the apexes (apices?). *Deneb Algiedi (delta Cap) needed to be naked eye visible or I would have no chance with the comet. By 17:25 I could see it. Sky Safari indicated that 45P was shining at mag +7.2 near the 3rd apex of an equilateral triangle made with theta Cap and a 6th mag star. There is a mag +7.3 star just near theta Cap. At 17:25 I could se it (averted vision), but not the comet. By 17:30 ,I suspected the comet, but could not be sure. 5 minutes later, it was apparent with AV, and by 17:45 with DV (only 7° above the horizon). When it was at the limit of AV, it appeared to be in one of two positions - it soon became apparent that one of these was a mag +7.5 star (just above the comet). I'm notoriously rubbish at estimating magnitudes, but I thought the comet was a tad fainter than the star. Mag +7.7 perhaps? 15 minutes later it was getting really tricky in the horizon murk, so I fled home to a warming whisky mac. Worth the effort! If you have a decent SW horizon, give it a go.
  12. Happy New Year! The latest edition of the Binocular Sky Newsletter is ready. As well as the usual overview of DSOs, variable and double stars, this month we have: * Several lunar occultations * Neptune easy to find near Mars * A remarkably difficult comet to challenge your skills To grab your (free!) copy, or to subscribe (also free) and receive it monthly, please go to and click on the 'Newsletter' tab. I hope you find it useful.
  13. As near as dammit identical.
  14. That is not a mounting bush. It is one of the screws that holds the hinge together. Those binoculars did not have mounting bushes - you need to get a hinge clamp; Opticron do one, and there is another kind usually called a "Kaiser clamp". Please do ask if you need more detailed advice.
  15. Took me a while...
