New scope or new Camera?

[matt_baker]

I'm stuck on deciding between upgrading my 130PDS to an 80mm triplet or saving a bit more to buy a Mono CMOS which would theoretically cost me £230 less for the camera if I sell my 600D and about £180 savings if I sell my 130PDS

Mono CMOS would imho give more of an improvement but also a steep learning curve 😁 you'd also need to factor in filters etc. You do open up the advantages of narrowband imaging also which helps with light pollution.
