Question EQ mount for my 10" newt

Hi all.

I'm starting to investigate the possibility of getting an EQ mount for my 10" newt.

While my EQ platform works great, it does make for some hard work when trying to track accurately at over 8m focal length. It adds untold frustration to an already frustration pursuit so I'm looking at reducing frustration and getting better images by putting my newt on an EQ mount.

I suppose it will also allow me to do some DSO photography, but that is not the main concern right now, as I can't bring my 350D or DMK to focus (at newt prime focus) without moving the mirror up the tube. Lunar/planetary photography is still my passion so any DSO photography that results is a secondary benefit and not my main purpose of getting an EQ mount.

So what sort of mount do I need, and how much do they cost?

I'm guessing that my 10" newt + imaging train (filter wheel + DMK + cooling system) will weigh something like 35lb (15-16kg). I'll put it on the scales tonight to make sure.

My budget is limited. Well, actually I can't afford it at all right now, but i'm just doing my research.

Will a HEQ5 hold it? EQ6? Orion Atlas? G8? A G11 is so far out of the budget it's not funny

Goto is preferrable, but I realise it will add extra cost in most cases. For now, accurate RA tracking (at over 8m focal length) with RA/DEC adjustments via hand controller is all I really need.

I'll probably keep my dob base for the option of swapping to it for visual work, though I might sell the EQ platform to help fund the EQ mount. Haven't really thought that far into it yet.

What else do I need to think about? Added costs?

I know I need to get some rings, for a start..

Input/suggestions most welcome.

Thanks
