I jumped from a 10" to 12" scope and had a little time to compare the two before the 10 " got moved on , the modest jump in aperture was
definately noticable at the eyepiece , I remember well looking at
ngc 2070 over two nights and noteing much more detail in the 12".This did surprise me a bit as reading some of the info online you get the impression the differance is quite small .My change was souly about makeing my own scope so the dollar outlay wasn't figured into it . I think this is were you'd have a good look at what you get back imo .. is that improvement worth shelling out cash at least the same as you have already spent?..Looking at both of factors these I'd go with more aperture
everytime unless portability is a major concern.

cheers graham
