JUST MY 2 CENTS I CONCUR WITH MORTON AND SATCHMO I cant understand?, youve got a quite portable excellent mak already! FOR WHAT ITS WORTH .IVE HAD refrs. A 4" UNITRON REFR from astro many moons ago for instance, and though great on planets, dsos where unresolved and dim.for portability ,optics, brightness, resolution , a 6 sct from celestron easily beat a 6' gold sw mak i had also in every facet and it was no slouch! the bd mak may be better, as fresh coatings, schott glass etc as would be a new intes.there seems to be very little to be gained going for a cumbersome refr of that length! anything bigger and it will be unportable
ps: everything needs some time to cool down optically, some longer than others ,theres NO free lunch! cheers
