About the ZWO Seestar S50

ZWO describes the Seestar S50 as a telescope, electric focuser, astronomical camera, ASIAIR controller, alt-azimuth mount, dew heater and filter wheel in one 2.5kg body. It uses a 50mm three-element apochromatic lens with ED glass at f/5 and a Sony IMX462 sensor. Choose a target in the app and it slews, tracks and stacks the image on your screen — and with the magnetic solar filter fitted, it images the Sun too.
