Description
ONAG® SC for APS-C chips up to 28 mm diagonally
New - Using the full frame for guiding (not just stars!) and also focusing in real time: https://www.innovationsforesight.com/education/full-frame-guiding-focusing/
Innovations Foresight is also in a beta test phase for our SkyWave (SKW) AI based wavefront sensing and collimation tool. The basic version will be integrated with SKG, here is a link to the topic:

Stop the frustration of flexure and small aperture guide scopes, or hunting for that magic star in an off-axis guider's tiny field of view at the distorted edge of the field of view and start using your main scope's full field of view to make guiding simply work the way it should - effortlessly.
Now with a highly-anticipated helical focuser for your guiding camera and adapters.
The ONAG SC is a new member of the On Axis Guider product line, it replaced the standard ONAG (discontinued).
To know more about ONAG technology please visit Innovation Foresight's eduction page.
The ONAG SC, when associated with FocusLock software, offers an unique solution for guiding and continuous real time auto-focus using Innovation Foresight's SharpLock patent pending technology. There is no need to interrupt your imaging session for any periodic re-focusing runs anymore, it happens in real time.
Innovations Foresight recognizes that ONAG's users may want to customize their ONAG solution to fit their setups, as well as to use adapters/spacers they may already own - A full kit with all adapters or the ONAG alone is offered.
The ONAG SC is optimized for APS-C, up to 28mm in diagonal, imaging chips.
All the ONAG SC optical ports, scope (SP), imaging (IP), and guider (GP), use a standard T2 M42 x 0.75mm (T thread) connections.
(Note: The maximum thread penetration length at the ONAG SC SP is 5mm, longer threads may scratch the dichroic mirror coating)
