Mark, the SW-252 is overpriced in my opinion you are paying way to much for this scope combination with a EQ6. The EQ6 on its own is abtut 1400, and a GSO 10" F5 (in dob configuration) could be had for much less. But I would recommend going for a 8" F4 or F5 scope. An Ideal one would be the Vixen R200SS.
There is no reason why one should have to pay 1000$ for a Synta 10" F4.7 scope. The same scope in the US sells for under 500$USD.

Eric's ezystyles uses this scope and you might ask him where he got his from. I really like the results he has got with his scope but i think its just to high a price given similar optics dont cost as much.
Just think for that money you could get premium optics from Mark at
http://deepsky.cia.com.au/optics/. Mark is a member here and makes very fine optics. I would rather spend the money on his optics then pay as much for Synta.
For comparison also look at the prices from Royce premium mirrors.

CM 10.45 - SM 10.45 wold cost you 875USD.
As your stated objective is Astrophotography, I would spent as much money as possible on the Mount. If you are a little paitent you could get a nice used Losmandy G-11 or a Vixen . And put a GSO 8" F4 plus a 80mm gudie scope on it. A good starting setup. Then you could save and buy better optics later.
Just my 2cents.
