Hello and thanks for the responses.

Thanks. Even as I typed the query, I knew the EQ6-R wouldn't handle that load for imaging.

Have you looked at Celestron CGX as an alternative?

I am fixed on a RC10, going from my 6 to 10 is a step up but from the 6 to 8, not so much in my opinion.
I dismissed Celestron early on as I use EQMOD. Although I do use SGP so it wouldn't need EQMOD????

With the $$ you save on the new mount, you can get an ASI1600 (weight = 500g) that will give you an image scale of 0.78 arcsec/pixel. Compare this with a RC10 f/8 with your current QHY9 and you'd be sampling at 0.7 arcsec/pixel. Almost identical, but the latter will be a lot more costly, and because the RC is photographically much slower, it will mean much longer subs (and so potential guiding issues).
Just a thought anyway...

And a good thought it is! Hmmm more to ponder with that. Maybe I should still get a RC10 AND a Asi1600!

With the 2000FL you are at some point going to want to go OAG which is going to extend the imaging train a tad. This means you either need a longer saddle or you will want more wait on the nose to get the balance so more wait on the mount. You want to avoid adding a guide scope..
If you can pick up a bigger spec mount, go for it. Could be pushing the EQ6/EQ6-R a bit.
on the plus side, you will be ready for the 14 you will definitely want next..once yo0u start going up..
The 10" by the way has an increased light gathering capability of 1.67 over the 8" so 2 inches will make quite a difference. Just note that the more recent GSO Truss scopes have the "a" on the end and resolved the focuser hanging off the back of the mirror issue..Dont know if that applied to the steel ones.
enjoy

I already guide with an OAG so should be good on that front.
As much as I would like a RC-A truss, the budget won't stretch that far. Shame because apart from anything else they just look do damn cool!
Moonlite sell a flange isolation thingy for the RC's so may look at that. Having said that I haven't seen a problem with my RC6.
So it looks like stumping up for a EQ8 is the much better, long term solution........
Thank you
Jeremy
