Hi russ,
Yup, a "sky straw" but if you get Polaris centered in the straw you might find it good enough to use for visual use but not for Gemini? GOTO operation. That said you might be close enough to use one of the built-in Gemini routines to pretty accurately get polar aligned. But this is a lot slower process than if you had a PoleMaster or a polar scope.?
