## Homework Statement

From my astronomy textbook: "The photograph that opens this chapter was taken next to the Gemini North Observatory atop Mauna Kea in in Hawaii. The telescope is at longitude 155 28' 09" west and latitude 19 49' 26" north. a) By making measurements on the photograph, find the approximate angular width and angular height of the photo. b) How far (in degres, arcminutes, and arc-seconds) from the south celestial pole can a star be and still be circumpolar as seen from the Gemini North Observatory?

## Homework Equations

The Small Angle Formula D=ad/206,265 where D= linear size of an object, a=angular size of the object in arcsec, and d= distance to the object

## The Attempt at a Solution

I really don't even understand what the two questions are asking for. Can someone get me started and possibly talk me through this one? Thanks.
