Based on your visit tonight here is a procedure for operating your 22 
inch Webster telescope.

During assembly, remember to put the shroud on prior to assembling the 
Upper tube assembly!

Assemble the scope.
Collimate the scope.
Align the Telrad with the scope so an object in the center of the Telrad 
is in the center when looking in the eyepiece.

Turn off the Argo Navis.

Disengage the ServoCat clutches.

Take the scope vertical until it hits the vertical stop.

Turn on the Argo Navis.

Press enter twice, then press exit.

Rotate the big knob until the display says "Mode Align Stars".

Select an appropriate guide star by rotating the big knob.

Push the scope so the guide star appears in the center of the eyepiece 
and Telrad.  Press enter on the Argo Navis.

Select a second alignment star on the Navis, move the scope to point to 
it and press Enter.

Alignment is now done, offset value, on Navis, should be less than 0.5.

Engage ServoCat clutches.

Press "Exit" on Navis, rotate big knob to "Catalog", press enter on Navis.
Select an object in the "Catalog" on the Navis, Press enter on the 
Navis, press the "Goto" button on the ServoCat hand pad .and the scope 
will slew to the desired object.

Have fun!
