How to Align a Finder Scope

A properly aligned finder scope makes locating celestial objects much easier by ensuring it points to exactly the same place as your main telescope.

Step 1

Choose a distant object during daylight, such as a church spire, radio mast or distant tree.

Step 2

Centre the object in your telescope using a low-power eyepiece.

Step 3

Without moving the telescope, adjust the finder scope screws until the same object sits in the centre of the finder's crosshairs.

Step 4

Double-check the alignment by moving to another distant object.

Final Check

After dark, refine the alignment using a bright star or planet if necessary.
