How to collimate polar finder

Retícula de buscador polar

To get the best results in tracking and guiding we need to have the best possible polar alignment.

The first step to achieve this is to collimate our polar finder so it is points in the same direction of our Rect Ascension axis.

NOTE: This method is recommended to be done by daytime

  1. Place the mount and point the polar finder at a distant object
  2. Rotate the mount 90º on the RA axis.
  3. Look through the finder, and use the collimation screws to bring the center of the polar finder's crosshair half the distance between the current position and the object we initially aimed at.
  4. Adjust with the screws of the equatorial wedge to point again to the same object we initially aimed to.
  5. Rotate the mount back to the starting position.
  6. Repeat the process until the crosshair is all the time pointing to the same object. This means that the polar finder is perfectly collimated.
