Tonight was the last straw for attempting to use my dual scope/spectroscope setup. No matter how tight I bolted down the skywatcher guide scope mount,something would shift causing a mis-alignment of the slits. Even changed guide scope mount out for guide scope rings and that was even worse!:( Works great if working on a small area of sky,but any meridian flips etc causes a shift and I am spending more time re-aligning the slits than actual observing……So now back to C9.25 on the EQ6 and swopping out spectroscopes each session.
