I am new to this forum, well I own a Celestron PowerSeeker 70AZ Telescope
http://www.celestron.com/astronomy/cele ... -70az.html
The above telescope was more of a toy but I want to be serious beginner now, therefore want to get an 8" deb telescope.
I researched and filtered these three telescopes, my budget is around $450 - $550 including the eyepiece kit
1) AT8D 8" F/5.9 Dobsonian reflector : https://www.astronomics.com/astro-tech- ... 18929.aspx
2) Orion Limited Edition SkyQuest XT8 Classic Dobsonian Bundle (The classicle is bit obselote in terms of built, focuser and some other points):

3) Zhumell 8-Inch Dobsonian Reflector Telescope: http://www.telescopes.com/telescopes/re ... escope.cfm
I know Orion is pretty proven but how is Astro-Tech and Zhumell? For Astro Tech, I researched the compnay and they seem to be more proffesssional handling real life space projects so it could be they are more "improved" with the design?
Focal lenght and aperture are the same in all. Which one would have better optics?
Would really appreciate some thoughts, advice and comments for my decision of buying one. Also would like some more suggestions.
