5.1 Focusing the Eyepiece

Adjust the focuser of your telescope or guide scope until the celestial object and the crosshairs appear sharp and clear. The eyepiece itself has a focus mechanism for the reticle; rotate the eyepiece body to bring the crosshairs into sharp focus for your eye.

5.2 Adjusting Crosshair Brightness

To activate the illuminated crosshair, turn the knob on the illuminator module. Continue turning to adjust the brightness level. Turn the knob until the crosshair is visible but not overly bright, which could obscure faint objects. Turn it off when not in use to conserve battery life.

5.3 Using for Guiding and Alignment

The illuminated crosshair is particularly useful for:

• Polārā izlīdzināšana: Aligning your equatorial mount with the celestial pole.
• Go-To System Alignment: Precisely centering alignment stars for computerized telescope mounts.
• Manual Guiding: Keeping a guide star centered during long-exposure astrophotography.

The wide 70-degree field of view helps in easily locating guide stars, while the precise crosshair ensures accurate centering.
