The iOptron Electric Focuser, also known as eFocuser, is crafted specifically for use with iOptron's Photron Ritchey-Chrétien (RC) telescopes featuring a dual-speed focuser. This handy gadget lets you dial in your focus just by pressing a button on a compatible iOptron hand controller. This eFocuser plays well with later models of iOptron mounts too.

But it's not just for iOptron scopes! You can also fit this eFocuser on other RC telescopes from brands like GSO, TPO (sold by OPT), Astro-Tech (offered by Astronomics), and Orion, as long as they have a similar dual-speed focuser setup.

What makes it even cooler? This eFocuser is ASCOM compatible, thanks to the embedded ASCOM driver in iOptron Commander software.
