I agree with Tom if you can swing the extra dollars go with the 8" F6
you get brighter images and more resolution. The cool down is not
significantly longer from an 6" mirror to and 8" mirror.

I think I've decided on a 6" f/8 dobsonain as my first real scope. 6"
is enough aperture to start to do deep-sky, and the long f/ratio
should make it less likely I'll get one with bad optics. I'm still
considering an 8" f/6, but I think I'll go with the 6" due to its
lower cool-down time.

Now...it seems my choice is between a Synta or Guan Sheng built dob. I
read in a couple of places that Guan Sheng is generally slightly
better optically. WHich brands are Guan Sheng? The only one I know of
is Sky Mentor from Khan Scope Center.
