Useful tips for all observations
Removing the finder scope
During an observation, when the desired target is acquired, it
is possible to remove the finder scope from its support. When
needed the finder scope can be inserted again.
This can be useful when the observer's head is in a position
where the finder scope becomes an obstacle to observation.
Using the indexed scale
The indexed scale on the focuser drawtube gives an accurate
indication on the focus position for various accessories.
Once the position for one accessory is known it is very easy to
approximate the focus position.
Due to the precision needed to reach perfect focus a fine
tuning is advised.

focuser knobs aren't in a convenient position.
