Next, learn a bit about optics, if you can. Many inexpensive Newtonian telescopes hit a price/aperture price point by compromising on mirror quality. This means that you will be paying for spherically-figured primary mirrors and not the more difficult-to-figure parabolic mirrors. Google on "spherical abberation" to see why you might want to consider paying a bit more for better optics.
Agreed, but 8" f/12 is a bit of a beast (and a specialty item, not found so easily I think), and decent parabolic mirrors are really affordable esp. Chinese ones. Good or even great starter scopes like small (say 6"f/8) dobsonians are available for $300 or so.
We often have questions about what telescope an aspiring amateur astronomer should buy. The "correct" answer can be elusive and is highly dependent on a lot of variables, including the expectations of the questioner, budget, storage capacity, available transport, etc. Rather than type all this advice over and over, I'd like to offer this post in the hopes that it can be made "sticky" so others can add to it, and it can remain near the top of the astronomy forum.
The best scope for you is tne one you enjoy using. Sounds like a success on that point. Beyond that you must decide what will please you in the future. Don't worry about getting down to magnitude 20. Eyepieces are your best friend. A good eyepiece makes a scope your slave, not master- and they are aperature insensitive. The best views for any aperature size comes from high quality low mag eyepieces.
The funscope is similar to my telescope(celestron firstscope).there is no difference between them except the company.in my opinion it is perfect for an amatuer.I myself am yet learning.and firstscope seems to be a decent scope to start with and so is funscope.
besides that I can't find anything ?
