Product overview

An off-axis guider uses a small portion of the main telescope's light cone for the guide camera, eliminating differential movement between a separate guide scope and the main optics.

Suitable applications

• Long-focal-length deep-sky astrophotography
• Refractors, Schmidt-Cassegrains, Maksutovs and RC telescopes
• Setups where a separate guide scope should be avoided

Included equipment

• Only 24 mm optical length
• Weight approx. 180 g
• 45 mm clear optical aperture
• M48 connection on telescope side
• M48 camera connection
• 1.25-inch helical focus for guide camera
• Microfocus around 0.05 mm accuracy according to product data

Backfocus and guide star

With an OAG, the main camera and guide camera must reach focus at the same time. The available backfocus of the complete system should therefore be calculated in advance.

Practical note

With reducers and flatteners in particular, check the full working distance. The OAG must fit inside the permitted backfocus.
