If I remember correctly, the last scope you were looking at was an 16 inch F5.8
DOB. At first that seemed ideal but now it appears you have come to realize
that a scope that is 8 feet long has some disadvantages.
This does not mean that all scopes larger than 8inches are so cumbersome as to
be unuseable, it just means you need to be careful in choosing.
Putting a nice mirror in that Orion scope is not going buy you the advantages
of 4 inches of added aperture. That factor of 2.25 in light gathering is way
too big to overcome.
My suggestion is to take it easy and check out some different scopes in person
and see what you think. A fast 12.5 inch scope can be quite portable, mine
fits in my '92 Escort and I can say that it out performs my XT-8 in just about
every way imagineable.
