wellcooked, would you agree with xevious on his recommendation? Is that also upgradable? Is it a better version in the series? If so is there another I might want to look at?

And finally after my onslaught of questions, what is the difference between an EQ1 and an EQ2 mount?

Oh and one more thing (for now), in the product specifications, is light grasp the same thing as aperature?

I would not, I have a 8" spaceprobe (got it for \$500 about 5-6 years ago) sure you can even make out the Orion nebula with this but the sky is always moving and you have to constantly adjust the scope, which is a pain because it very difficult to make small movements. I could never get a good camera image unless I was taking a shout of the moon. I have tried out equatorial mounts (at a local astronomy party (yes geek fest)) and I was blown way. With an equatorial mount you just align it up, aim at the celestial body you want and look at it, as the sky moves just twist the dial and you stay totally on track. Clear vibrationless images.

It depends on the Dobsonian... some Dobs as wellcooked says, are horrible! But some, like the Orions and those made by Discovery, are quite good. The chatch is: Astrophotography will be very hard to do.

For casual use, I am still a fan of the tried and true Alt-Azmuth system - and Dobsonians are Alt-Azmuth. Sure tracking isn't as easy especially at high magnifications, but for wide-field deep sky images, Dobsonians are a NICE option. It is another one of those questions that boils down to what you want to do. For just looking around, Dobsonians are OK. If you want to do some serious work, only an Equatorial will do.
