You can also get barlows that have the lens unscrew to give you a x1.5 screw on barlow cap for EP's, and the x2 with the tube extender.
Using the x1.5mag would allow you a 9mm/6mm combo from the same eyepiece, which may be more useful. The ER from the x1.5 barlow will not be reduced by as much either.
I haven't tried any morpheus ep's, but the 9mm with a x1.5 barlow might prove a good ep for clear nights or superb nights. You still can go with the x2 barlow should conditions ever allow it.
