Beg to differ.
I often use the internal guide chip for NB.... it just needs a bit of planning (via a sync to TheSky with an instrument rotator, guide stars are pretty easy to find.)
Better still is using SBIG's Adaptive Optics a remote guide head with the AstroDon MOAG....you can get some incredibly tight stars with AO guided narrow band.
.... In short SBIG's system integration is in my opinion, the best available.
I must admit STX secondary systems have been slow to come to market, but am confident differential guiding etc. will pave the way for some very impressive images in the not too distant future.
