this focus system is coming to the Lodestar guide camera + OAG
Let me provide some further information on this and related matter:
OPTEC and Innovations Foresight are working together for providing a retrofit-kit for Lodestar owners which will allow the SharpLock (SL) real time auto-focus technology (implemented in FocusLock software) to be used with some OAG models.
We expect to launch this new patent pending accessory during NEAIC/NEAF 2016. Its is an interesting option for setups having limited back focus, such as Newtonian, for which the ONAG solution may be challenging to mechanically fit in.
Also new development are coming for providing full frame auto-guiding and real time auto-focus (SL) capabilities while using an ONAG and a large guiding chip, since all ONAG devices now features a guider port supporting sensor diagonals up to 28mm (APS-C size).
In this approach auto-guiding will not required the selection of any guide star anymore, details to follow... This may be specially useful for robotic/remote operations.
