(1) Does anybody here use their binoculars for astronomy?
(2) More specifically, has anybody used 8x42 and/or 10x42 binoculars for astronomical observation? If so, what have the results been like?
(3) Even more specifically, has anybody used Nikon Monarch 8x42 and/or 10x42 binoculars for astronomical observation? If so, what have the results been like?
I'd really appreciate any experiences you'd care to share on suitability, objects visible, clarity, colour, brightness, etc. etc.
Thanks in advance! 
I have used a variety of binoculars for astronomy. The main ones currently being 7x42s, 15x45 IS (Imaged Stabilized), and, more recently, 12x36 IS. In the past I used a pair of 14x70s.
I am not quite sure what you mean when you ask about "results." Binoculars will reveal far more than the eye alone, but they are more a compliment to rather than a replacement for a telescope. They provide low power, wide field views that are not available in most telescopes. Binoculars are great for providing wide, star filled vistas where the skies are dark. They are also nice and portable and easy to use. Anyone owning binoculars would probably enjoy some time viewing a dark, moonless sky.
You can see examples of most types of deep sky objects - nebulae, galaxies, star clusters, double stars, and so on with binoculars. The Moon reveals a lot of detail, and you can see the four bright moons of Jupiter. They do not approach the views provided by a telescope, however.
What do you wish to observe in the night sky?
Clear skies, Alan
Hi Alan,
Thanks for your reply. I wondered whether there were any fellow astronomers here. I have a Meade ETX105 scope. 
My 10x50 astronomy bins were recently stolen and I'm therefore about to buy a new pair - but I really need a good pair of nature/birdwatching bins too, and I can't afford to buy separate dedicated astro-bins as well right now, so I won't be buying replacement 10x50s or above. I'm looking at buying a pair of either 10x42 or 8x42 binoculars - probably Nikon Monarchs.
That's why I asked whether anyone had used these particular bins, or other bins in this size range, for astronomy - as I previously used 10x50, I'm not sure how the 8x42 or 10x42 will compare for night sky observation, so am curious to hear others' experiences with these. I would use them to complement my ETX scope, for a wide range of the usual observations - from Moon to Messier - as you have already described.
Could you tell me a bit about how your different sized binoculars have served you for astronomy? What deep space objects became visible with which magnification/aperture and with what quality of image, etc.? Give specific examples of popular clusters, nebulae etc. if you like. 
Clear skies to you too, from the UK. 
Clear sky here tonight...
Moon waxing gibbous, low and extremely bright...
Mars looking splendid these nights...
Saturn returning for the Autumn...
Nights getting longer, darker earlier... only problem is they get colder too!
