Is your primary interest in photography or visual?
Does it have to be a fork mount? Does it have to be an SCT?
For pure visual, the fork mounts are great.. easier to setup and align.

I have a 12 inch dob, so whatever i buy i would be dissapointed if its light gathering power was not at least around that of my dob. I guess i miss out on good views of open clusters but should still be able to see orion et al in the field of view with my 16mm nagler 3048 / 16 = 190 by and 82 / 190 = .43 degrees. Maybe i would need a lower power nagler?
A good eq6 mount with goto costs a packet and may not be stable with a 12 inch dob. I also like the idea of a sct as far as observing angle is concerned and basically have always wanted a large aperture scope on a driven goto mount. So at the moment fitting a argo navis doesnt cut it as i still have to move the scope and i dont think an eq6 would be very stable with a 12 inch dob, for viewing, maybe photography would be ok..
There is no such thing as a 'last' scope but i am hopefully thinking this will be my last scope and in the future i will want to do photography.
This is why i am thinking of the celestron which has a better mount than the lx90gps. I am assuming it has a better mount and that the eqivalent meade one is the lx200r which is far more expensive.
Do you reckon i would be dissapointed with the 1 inch less aperture, around 19% maybe.
Anyway it is hard to know which one to buy.
Thanks Paul
