    I posted this in someone else's thread and did not get an answer, so hopefully someone will help...I saw a pair binoculars in that camera shop in Blanchardstown, cannot remember the make, but they were 16*50, and were not too expensive, about 130 or 150 IIRC. Would these be any use whatsoever. I have a pair 10*30 at home, and you really cannot see very much, even of the moon, would 10-50 allow me to see much more detail, or would 16*50 be better.

    Well the first number is the magnification and the second is the the size of the objective lens. For astronomy you're supposed to have at least 7 magnification I think, and at least 50 objective lens. When you divide the objective lens by the magnification you get a number related to the field of vision you get with the binocs. I read that 7mm is ideal for most people as it's the same size as your eye so you maximise the field of vision. 7x50 is a common choice for that reason. Basically 10x50 would give you less magnification but a larger field of vision than the 16x50. Best thing is to try them out before you decide I'd say. And Google for info. Because I barely know what I'm talking about here.

    Also because you are using a higher magnification in the 16x the image will be darker. Personally I would go for 10x50 or 10x70. You won't see that much more with the 16x, some more lunar detail perhaps. My binoculars are 10x50's from lidl costing EUR20!

    I have a pair of 10 by 50s myself too. They are fine for astronomy.

    The ones I got at least were on a secial they did, I dont think they have a regular supply. Its worth checking out their website every week or so as they often have astronomical related goodies, binoculars, telescopes, humidity detectors, hand warmers... :)
