  1. Not entirely sure, so do check with others, but: A photo or two would help but, if they are the ones I think they are, I think the objectives are held in place by retaining rings. If so, you'll likely need a peg spanner to remove them. It probably collimates with eccentric rings, so you'll need to mark the exact position of those before you dismantle it; also a good idea to return the lenses in the same orientation - marking their rims with a pencil can aid this.
  2. At 20x, it will be difficult and you'll require a night of good seeing (i.e. steady air). I have, on a couple of occasions, managed to fleetingly see dark spaces between the ansae and the planet's disc with a mounted 15x70, Also made difficult at present by Saturn's low declination. Think of a 20x80 as being a great instrument for open clusters, that will also enable you to detect other DSOs. Markarian's chain is now available - on a dark transparent night, you should be able to see more galaxies than you can count.
  3. Parallelogram and recliner (see avatar).
  4. No, I don't. - but give me a while, and I think I can do it for you. I'll PM it to you when done.
  5. In addition to Infocus (above), you can try Castle Cameras: https://www.castlecameras.co.uk/used-equipment/used-optics/used-binoculars/c276 ...or London Camera Exchange: https://www.lcegroup.co.uk/Search/?SearchStr=used+binocular&SUBMIT.x=0&SUBMIT.y=0
  6. If you can't see the tab, you can use the menu (3-bars).
  7. The March Binocular Sky Newsletter is ready. Not a lot of binocular stuff going on in the solar system, but in addition to the usual stuff on DSOs and variable and double stars, this month we have: The "realm of the galaxies" is back ... ...and we still have lots of open clusters I hope it helps you to enjoy these chilly late winter/early spring nights. To pick up your free copy, just head over to http://binocularsky.com and click on the Newsletter tab. You can also subscribe (also free) and have it emailed each month.
  8. Indeed. And the deluxe "cranked" version even incorporates clearance for astronomer's belly. (& glad that at least one person found the suggestion to be useful! )
  9. My next door neighbour got that binocular for his birthday. We put it on a Manfrotto #075 tripod with a #222 trigger-grip head. Ideal.
  10. Indeed. It's a lovely little binocular. My review of it is at http://binocularsky.com/binoc_reviews.php
  11. Simply that I found the view in the Vixen 6.5x32 to be more satisfying; not significantly fainter than the 10x50, but better colour and also a steadier view and a sharper image across the field of view.
  12. Short answer: any of the above. Long answer (L-R) - under Bortle 4 skies, in the order in which I tried them: Lunt 16x70 - Exceptionally easy, green-blue colour obvious. Rank 1 Lunt 10x50 - Very easy to identify, but colour not as obvious as in the 16x70, but still detectable. Rank 3 Vixen 6.5x32 - Not quite as bright as in the 10x50, but colour was better; still easy and obvious. Rank 2 No-name plastic lensed 4x30 (free with a part-work) - Extremely difficult owing to horrendous spherical aberration. Could see it in one tube only at a time, with eye position being critical. Not recommended. Rank - 6 Vixen 2.1x42 - Not bright, but still quite easy. Rank 4 Celestron freebie 2(?)x25, cardboard body, plastic lensed - Inspired to try this by the success with the little Vixen. Yes, it is possible; faint but easy to see once you have acquired it. Rank 5 In reality, I could only recommend the three on the left (or equivalents - say anything of reasonable quality, 6x30 or bigger) for relatively new observers, but it's fun to see what's possible with the freebies.
  13. There is, but it's terse. Also I did do one for Sky at Night a while back: http://www.skyatnightmagazine.com/feature/how-guide/how-collimate-binoculars-astronomy Also, see Bill Cook's excellent new book: Understanding & Attaining 3-Axis Binocular Collimation (review in the pipeline)
  14. I expected that to be a nuisance, but a slomo in each hand was fine. Alternatively, you could put short knobs on the slomos.
