Astrodon and Lumicon Off-Axis Guiders are the most robust and well constructed off-axis guiders available. Take your guiding to the next level. Be sure to browse the links below for useful information in selecting your OAG components.
Backfocus Calculations: In order to get the guide camera and main detector both to come to focus properly the camera side connection lengths need to be calculated and the corresponding stock adapter selected or custom adapter made. A detailed discussion of how this simple calculation is performed can be found here.
Adapters: The MonsterMOAG is sold without telescope and camera / filter wheel adapters. We offer (separately) a series of standard adapters that connect common devices to the guider body, however it is common to need a custom adapter to get everything connected properly. For this, we recommend using Precise Parts to design and make the adapters you need. You can see our video discussion about using Precise Parts here.
