The reason why I suggest you keep the money that you intend to spend on getting a bigger bino is simple. First of all, bigger aperture is good for fainter objects, but it's not going to make much of a difference from your 10x60. You probably won't even notice, nor recognise the fainter stars you see. The weight, though, will be significantly heavier. And he higher magnification will reduce your FOV so open clusters like Pleiades may not fit in nicely. I feel that Pleiades is best observed at around 8x to 10x magnification as you can see the blue glow more in lower magnifications.guangwei wrote:I don't think i can save up for a telescope for now as school is starting soon and i don't have a part time job currently. Maybe in the future when i work. (: So for now i think i would want a decent giant astro bino maybe a 15x70,20x80? Yesterday's night sky pretty much clear and when i use my 10x60 bino i could see quite alot of stars in the sky and many faint stars. So i was wondering if i get a better one, i could see even more. Maybe i can join you guys for observation sessions and can learn more! I live in the east area.
Getting a bigger binoculars will require a tripod, and it will cost you like $300 or more in total. While a scope, like my 127mm maksutov, will cost no more than $1000 for a complete setup. You're paying almost one-third of the price of a full scope setup, for a bino setup. And personally, I feel that a binoculars is supposed to be a grab and go, portable equipment. If you need to grab along a tripod, it's really not as portable. And the tripod you get for your binoculars, cannot be used for a scope as it's weight load is definitely much lighter.
That is why I suggest you keep your 10x60 binoculars, get a star chart, and get familiar with the sky. And you can always join scope-owners for observation sessions to take a look through their scopes. And if you mean start school as in Poly, then you still have 2 months to go. Find a job, and you can definitely save up at least $1000 within these 2 months. I worked for 1 and a half month after my Os before I saved up enough to get my scope in December. Right now I'm already saving up for my Lumix LX3 and laptop.
