iOptron iAFS2 2\u2033 - Electronic focuser for precise and comfortable focusing<\/strong><\/p>\n\n\n\n

The iOptron iAFS2 2\u2033<\/strong> is a powerful automatic focuser that helps you get sharp images even in heavy astro setups. You can mount it along the optical axis without fuss. Its smart design with iLock\u2122 technology keeps heavy systems stable, so your image stays sharp while you rotate the telescope.<\/p>\n\n\n\n

\"iOptron<\/figure>\n\n\n\n

You can choose from three focus modes: manual, motorized or via computer. The manual focus wheel lets you get into focus quickly. A built-in temperature sensor automatically adjusts the focus as it fluctuates, keeping your details in focus. Thanks to its solid metal housing and dirt-resistant surface, the focuser remains reliable even in cold or dusty conditions.<\/p>\n\n\n\n

The iAFS2 2\u2033 comes with a 2-inch visual back and USB-C cables for easy connection to your computer. It is compatible with ASCOM & INDI and offers an accuracy of 0.6 \u00b5m. Perfect for those who want maximum control over focusing both visually and photographically.<\/p>\n\n\n\n
