 from BBLabs, you’re on your way to a whole new level of accuracy and ease while observing the night sky.

+At the start of each session, you may need to do three things:
+
+- Check and adjust camera focus
+- Align the PiFinder by telling it where your scope is pointing
+- Check the status of the GPS lock

+You may not need to do all of these things at the start of every session.  The focus should generally remain 
+the same from night to night and if you leave your PiFinder on your scope you may not need to adjust the 
+alignment each time.  To perform most functions the PiFinder will require a GPS signal, and this should
+happen automatically, but the GPS Status screen can be used to monitor progress towards a lock and also 
+boosts the GPS signal.  This can help in marginal situations or to speed things along.

+^^^^^^^^^^^

+There is a GPS status indicator in the PiFinder title bar which will flash while the PiFinder is 
+searching for it's position and time.  This indicator will turn solid once the PiFinder knows where
+it's at and what time it is.  You can monitor this process and activate a special signal boost mode
+via the 'GPS Status' menu item in the 'Start' menu.

+If you are using the PiFinder under partially obstructed skies, or locking is just taking longer than
+you like, you can leave this screen active to enhance the GPS signal by temporarily stopping the camera.
+Like most electronics, the camera system generates electromagnetic noise that can make it more difficult
