The 150 throws up a VERY noticeable CA - you would NOT be able to process it out. It is purely a visual instrument only.
I had one - damned dinosaur of a scope too. You'll need a decent mount to push it too - an EQ5 won't cut it. Maybe an HEQ5 but I'd go NEQ6 if you insist on buying the brontosaurus.
They make a decent solar scope though
Honestly, for imaging, FUGGEDABOUTIT.
