SKY - Updating Alignment
Sometimes you may find it useful to update your alignment during an observing session. Let’s say you just slewed to
M51, the Whirlpool Galaxy. You decide it would be nice to do an alignment here to increase your accuracy in this part of
the sky. You can align to M51. Here is how to do this.
BUTTON or ACTION NOTES DISPLAY

menu, with the Messier catalog

CHANGE - Changing Alignment Stars
The Ultima 2000 uses two alignment objects to align itself to the sky. If you align to a third object, the telescope replaces
the alignment information of one of the previous two alignment objects. The software automatically replaces the
alignment information of the nearest object to the new object. This ensures that the alignment stars are not too close to
each other.
