If you're looking for a heavy duty GoTo mount for all your observing or astrophotography needs, the Orion Atlas EQ-G computerized GoTo telescope mount is perfect. It supports up to 40lbs and finds over 42,900 celestial objects with pushbutton ease.
For producing striking, high-contrast color CCD astrophotography of emission nebulae with a monochrome CCD camera, you should use extra-narrowband filters. The 1.25" Orion Extra-Narrowband Hydrogen-Alpha filter is one of a set of three filters.
