Product Description

The Innovations Foresight ONAG SC is a new member of Innovation Foresight's On Axis Guider product line, it replaced the standard ONAG now discontinued.

To know more about Innovation Foresight's patent pending ONAG technology please visit our education page on this matter.
The ONAG SC when associated with FocusLock software offers an unique solution for guiding and continuous real time auto-focus using our SharpLock patent pending technology. There is no need to interrupt your imaging session for any periodic re-focusing runs anymore.

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, so they've offered the opportunity to buy your ONAG unit and select separately adapters/spacers. They've also offered kits for various configurations, such as full kits with all the Innovations Foresight adapters/spacers you may need with your ONAG for most standard setups. 

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.

(Warning: The maximum thread penetration length at the ONAG SC SP is 5mm, longer threads may scratch the dichroic mirror coating)
