accuracy.

1. Use a go-to command to slew the telescope to a target in the area of sky where you want increased accuracy.

2. Centertheobjectintheeyepieceusingthehandcontroldirectionalkeys.

3. Press and hold down the ESC key for 2 seconds. The hand control will display “Re-center”andthenameofthereferenceobject 

 willappearontheLCDandblinkthreetimes.Ifthego-tocommandissentfromanexternalplanetariumsoftwarethroughthe 

4. MakesurethattheobjectisstillinthecenteroftheviewandpressENTER. The SynScan AZ will record the amount of

correction required and will recalculate its model of the sky. The pointing accuracy in this particular part of the sky should be

 greatlyimproved.

Hint: The result of the PAE is stored in the hand control even if the power has been turned off but will be erased if a new alignment

procedure is performed.
