Adrian is right. The SCT is no better than a newt, it just looks hi-tech cause they come on fork mounts that already go buzz click.
In fact I've always preferred the view through newt's as opposed to SCT's. More contrast, less central obstruction, wider field of view (shorter focal length).
There's nothing you can do with an SCT that you can't do with a newt, and newt's are more customisable, easier to cool.
The only issue with a newt on an EQ mount is the eyepiece position - you need to be able to rotate the tube in the cradle so you can get the eyepiece at a comfortable position even when it's 2 metres or more off the ground.
Although SCT's and refractors suffer the same issue, except in reverse - you can end up kneeling on the ground.
I love newt's. I loved my 10" and now I love my 12". My 10" was dob mounted for most of its life and only sat in an EQ mount once or twice. The 12" now sits in an EQ mount, but like Gary said, it's convertable back to a dob at any time.
It's still got the altitube hubs on and i've still got the dob base. Best of both worlds.
