   * Is the star too low or obstructed by a tree or dome? W1 and S2 have trees nearby that can obscure the star below 40 degrees. Refer to the horizon maps to see if they are the cause.
   * E1 does not track past 218 degrees azimuth. The finder camera may be needed to find the star again. It will be off in azimuth, but should still show in the finder.
-  * If a star does not appear in the finder either, such as after a dome server crash and restart, finding a bright star, the moon or Jupiter can be used to get the scope pointing correctly.  Anything brighter than Vmag 1 will show on the Spycam 1 view and can be used to get the scope close enough to find it in the finder, then ACQ. It will appear just below the top bar of the telescope, centered left to right.
+  * If a telescope is lost and star does not appear in the finder either, such as after a dome server crash and restart, a bright star, the moon or Jupiter can be used to get the scope pointing correctly. Anything brighter than Vmag 1 will show on the Spycam 1 view and can be used to get the scope close enough to find it in the finder, then ACQ. It should be placed just below the top bar of the telescope, centered left to right using the telescope paddle. You may have to pan up and down to see it move through the finder view. Use the obsgtk ADJUST tab scope paddle and set a step of 3000 and go up and down after centering it in the SPY 1 view below the top telescope bar. When you get it centered in the finder, manually init the scope to the AZ and EL on the MANUAL tab of the dome gui to one decimal place. Use Stellarium online or any resource to get the current position. You should then be able to slew to a star and center it in the finder, then ACQ and init on the obsgtk to get the scope back to usual.
