I should add, I'm coming from a spectrum 60mm upgraded PST, and a home modded 80mm PST, but both still only had the BF5.

I found both to be a considerable step up from the PST, but as I am going to make solar (and spectroscopy now that the bug has bitten me..damn you Merlin!) my main astronomical passion, I want something that is a really good step up from the modded PSTs. I don't want to get upgradeitis in too short a time... (yeah, I know

)
The scope would be going on an EQ6Pro or a HEQ5Pro.
