    When do you think SKU # CEL-71012 will be back in stock? Or what other options do I have, as Im after binoculars for astromony and bird watching.
    Unfortunately we most likely won't be getting them back in stock :( I would recommend going for either the Skymaster 20x80 (http://www.ozbinoculars.com.au/celestron-skymaster-20x80-binocular.html) or the 15x70 (http://www.ozbinoculars.com.au/celestron-skymaster-15x70-binocular.html) instead. For astronomy, I'd recommend going for the two above. For birdwatching, the best specs is 8x40 which is a good magnification and keeps the field of view wide. 40mm binoculars would also be small and light enough to carry around for birdwatching, whereas astronomy binoculars are usually above 50mm or 60mm in objective lens size and are typically suited to be set on a tripod instead of being brought out. I'd have to say, good birdwatching binoculars wouldn't be suitable for astronomy, and good astronomy binoculars wouldn't be suitable for birdwatching. That's because the magnification and aperture for both birdwatching and astronomy are not very similar. Birdwatching is best at a lower magnification of about 7x or 8x and about a 40mm aperture, whereas good astronomy binoculars go to higher magnifications of 15x above and very large 60mm to 80mm apertures. For birdwatching, I can recommend the following: Bushnell Natureview 8x42 (http://www.ozbinoculars.com.au/bushnell-natureview-8x42-roof-prism-binoculars.html) Bushnell Trophy XLT 8x42 (http://www.ozbinoculars.com.au/bushnell-trophy-xlt-8x42-binoculars.html) For astronomy: Celestron Skymaster 15x70 (http://www.ozbinoculars.com.au/celestron-skymaster-15x70-binocular.html) Celestron Skymaster 20x80 (http://www.ozbinoculars.com.au/celestron-skymaster-20x80-binocular.html) If you want something that you can use for both, you can try something with a variable zoom magnification. This will let you see closer up for birdwatching and zoom out more for astronomy. It'll be similar to the 20-100x70 you were looking at, but the magnification for our other binoculars can't reach as high as 100x like on the Celestron. I do have to say as well that most variable zoom magnification binoculars are not as long lasting due to them having more moving parts inside them. Some suggestions: Saxon 12-36x70 (http://www.ozbinoculars.com.au/zoom-binoculars-saxon-12-36x70.html) Barska 10-30x60 (http://www.ozbinoculars.com.au/barska-10-30x60-zoom-escape-binoculars.html)
