Hmm... should be with 20x80 you'll see more with a neck pain, with 10x50 you'll observe more comfortably. Ha ha hawith 20x80 you'll see more, with 10x50 you'll observe more
Have a nice day.

HAHA ... guys! You're confusing the porr man ... 
Ok let me tell you why I say I recommend a 10x50 instead of a 20x80 at first.
What WX says is true, you'll definitely see more stars with bigger bins at higher mag. There are a few things to consider though because you say you're a beginner and this is your first optical instrument for Sky Watching.
1. 20x80 has a relatively much smaller field of view. Common FOV of 20x80s is about 3.2-3.5 deg, which is pretty small for learning the constellations through a scope. A 10x50 will typically give about 6.5-7.5 deg FOV depending on which one you get. That will give you almost double the FOV and will be much much easier for identifying star patterns within the FOV and even for generally pointing at something, that you can see with your naked eye. Wih a 3.5deg field, you generally need to do some hunting.
A good example of how FOV helps is with the Southern Cross. Just 1 hour ago, I couldn't see Delta Crucis naked eye and used my 12x50s. Crux just fit very snugly into my 5.5deg FOV for me to recognise it as the Southern cross with a slight shifting of my binos. With my 20x80 I couldn't fit barely fit 2 stars of the crux into the very edges of my bins at the same time. If I were a beginner wanting to confirm if that were Crux, I would have absolutely no idea.
2. You can't handhold a 20x80 for decent viewing. Everytime you bring it out, you have to have a decent tripod setup just to get a decent view. With a 1050, you can just grab it on a clear night, even if you have 15 mins and just use it to sweep the sky or jump from constellation to constellation.
3. There are alot of objects you can find even with 10x50 or 7x50 binos that should satisfy you before you get your first scope. I find that learning the sky will be more fulfilling than just being able to see more detail in a few objects. Learning constellations will be much easier with wider fovs.
4. If you're new to Star hopping, 20x80s will show dimmer stars (more stars) and it will be a little more confusing to Star Hop after seeing so many stars.
Having said that, if you wanna get a pair of 10x50s AND a pair of 20x80s at the same time, who am I to stop you? Let me just say that you would be happy with both, just that if you were to choose just one, I would say 10x50s would be the way to go.
All the best finding the perfect binos for yourself and enjoy your journey among the stars!
Clear Skies to you!

Hi Klutz,
I have a pair of Russian 10x50 binos with me. I am currently not using it, so i can lend it to you for you to use during observing, and also to compare with binos of different settings. It is not for sale though.
Your location is in Tampines? If you are free, you can just give me a call on my hp (9137 3921) or pm me and i can pass the binos to you. Daytime also can , not neccessarily to be during obs session cos if during observing, the weight of my telescope is enough to kill me. =)
Best regards,

I miss the place where stars shine bright, to gaze upwards in awe of the sight
THANK YOU SO SO SO SO MUCH, Junwei!!!!!!!!!!!! I'll arrange with you tomoro. 
By the way, I had a great session last night, all THANKS to Weixing!! He's been real kind, showing and explaining the stars to me, teaching me how to read the star map etc!! That's my very first encounter with moon's big "pimples" ... haha... it was so beautiful...
Thanks, Weixing..!! Looking forward to attending your next session.

YEah ... especially since you live in Tampines (if I remember correctly) .... You can meet WX more often ....
He's a good teacher ... not only in Astronomy ... you can ask him bout Taiwan politics also ... HAHAHA ... Right Weixing??
