Introducing the most versatile inline focuser available, the iOptron iAFS™ focuser with iLock™ technology. Utilising a lead worm movement is the key to the iAFS focusers patented design; this passive position locking system secures most any payload
(imaging train) at the stopped position, maintaining focus even as the instrument angle is changed.
The iAFS incorporates three focus modes;
- USB (computer control)
- on board directional buttons (for powered manual adjustments)
- a manual focus wheel
Other features include a built-in temperature sensor, multiple USB-C ports, solid all metal body, fingerprint resistant exterior surface, 0.6 micron movement resolution, position limiters to prevent over runs.
It come standard with a two inch visual back and optional telescope adapters to fit various OTAs are available. Contact us for more information on adapters.

I am delighted to write a report for this product. It is extremely well made and combines a manual as well as electric function for focusing. This is important to me because with my other electric focuser, I was unable to use the telescope visually without having to dismount it. Now I am able to use it visually.
The focusing function allows very precise control. Unlike my previous focuser, there is now no problem from Schmidt Cassegrain mirror slop. I can now search for focus by adjusting in and out of focus and then when focus is found, set the counter to zero. I am a planetary imager and can now be very precise in searching for focus - even during a video capture. When experimenting beyond your "zero" point one can always return to that point precisely.
I have no hesitation in recommending it.
Cheers,
Paul Mallinson
