【實用攝影app】PS for StarAdventurer|最夯免費app-綠色工廠好玩App

For users of StarAdventurer camera mounts. Provides a real time display of where the polar reference star(s) should appear in the polar scope reticle.For the northern hemisphere the reticle needs to set to its home position and the user only needs to match the position of Polaris as displayed by the app.When in the southern hemisphere the reticle needs to be rotated to the correct angle which should be the same as that displayed in the app. Polar alignment is achieved by adjusting the mount till the four stars in the octans asterism are moved into their circles. To get precise alignment you may need to fine tune the reticle rotation to get the best match.This app will automatically calculate the polar reference star positions based on the time from the system clock and the location provided by location services.
