Cheap Dobsonian Telescopes
Just wondering. Which telescope is better in your opinion?
SAXON (Dobsonian)
http://www.ozscopes.com.au/dobsonian-telescope-saxon-12inch.html
SKYWATCHER (Dobsonian)
http://www.ozscopes.com.au/dobsonian-telescope-skywatcher-black-diamond-collapsible-12-inch.html
The Saxon one is cheaper though.
Is there a big difference between them besides size (and transportation)? I care about how far you can view and the quality of the images.
Which one can see more further and more higher quality image?
But if there's not a big difference (almost identical) between them two, I'd get SAXON.
Ignore the rest above...
I'd ask a new question but... I reached the daily limit 
I still need to research about peoples opinion on telescope.
On the site below

Which telescope would you recommend for around AUS 1000 dollars? And why?
Thankyou 
Saxon and Skywatcher telescopes are of equivalent quality and some of them are the same telescope marketed under different names.
They are both made by Synta in China.
The Flex-tube design is more expensive to produce but is easier to transport and can still be set up in a few minutes.
It has a focal length of 1500mm against 1200mm for the Saxon, making the Flex-tube a little better than the Saxon for planetary observations but the Saxon is better for deep sky objects where image brightness is more important.
A 10mm eyepiece giving 120x on the Saxon will give 150x on the Flex-Tube but you can use a smaller focal length eyepiece to get 150x on the Saxon of course.
The difference though isn't very great and both are short focus telescopes for their size...F5 and F4....which will work very well for deep space objects like galaxies and nebulae and well enough for planets to satisfy all except specialist observers....or at least those with reasonable expectations of what a telescope can do.
A 12" gathers plenty of light for high power planetary viewing and works very well for planets at F6 and above and superbly at F8 but then becomes very bulky.
At high F ratios a catadioptric design is far less bulky and more convenient to use but they are very expensive at large apertures.
The Flex-Tube's focuser is a Crayford type which allows fine smooth focusing, superior to a rack and pinion focuser.
The Flex-Tube has had a number of good reviews. Here is one of them.

Pretty well all Skywatcher telescopes perform well for the money and are recommended by myself and other experienced amateur astronomers on here as being a brand to look at when choosing a telescope.
The Saxon is actually the same as a Skywatcher 12" model but with a different name.
It has a pyrex mirror and the same style of Crayford focuser used on the Flex-Tube.

Here is a Skywatcher 12" using the same mirror and focuser as the Flex-tube but otherwise of similar design to the Saxon, and uses a traditional tube

Cheaper versions using a plate glass mirror and a rack and pinion focuser are also available under various names but almost all made by Synta and have about the same optical performance but the mirror will need to cool longer than a pyrex mirror which is less affected by temperature changes.
The 60" reflector on Mount Wilson has a plate glass mirror as do several other large vintage professional telescopes and thousands of amateur telescopes.
You can buy a Crayford focuser for around AU$150 and upwards and fit it easily to replace a rack and pinion focuser if you wish to upgrade later.You need care but it's just a bolt-off bolt-on job, being careful not to drop anything onto the mirror. Keep the tube horizontal and you'll be OK.
To summarise, either of those telescopes will do a good job for lots of sky objects from sweeping rich star fields, finding faint galaxies and looking at the Moon and planets, and the differences between them for practical observations are not great, with any advantages one has over the other being easily outweighed by diiffereing sky conditions like transparency and the steadiness of the air from night to night so it's really a matter of which telescope you like best.
Have fun.
