Change filters in seconds<\/strong>
The iOptron iEFW makes filter changes quick and effortless. No more fussing with screws or loose caps. Just turn the wheel or use the software, and you're instantly ready for the next shot. That way you don't waste time while shooting and keep your focus on the sky.<\/p>\n\n\n\n

Always the right filter at hand<\/strong>
This motorized filter wheel has room for 5 filters. You can use 1.25\u2033 filters with frames or 31 mm filters without frames. Ideal if you often switch between LRGB or narrowband filters. The compact build keeps your setup light and well balanced - perfect for astrophotography with small to medium-sized telescopes.<\/p>\n\n\n\n

Smart design, smooth operation<\/strong>
The iEFW operates entirely through a single USB-C cable. No extra power supply needed, no tangle of wires. Connect it to your laptop or PC and control everything digitally. The quiet stepper motor turns smoothly and precisely, so your filter is always exactly in place - without vibration or lag.<\/p>\n\n\n\n

Built for reliability<\/strong>
With a sturdy metal body and an optical length of only 20 mm, the iEFW fits easily between your camera and focuser. This means your image sharpness is maintained and your optical path remains virtually unchanged. A practical upgrade that will make your nights easier and more efficient.<\/p>\n\n\n\n

Your benefit of purchase<\/strong>
When you buy from a specialized dealer, you not only get a quality product, but also help from real experts. Whether you have questions about assembly, software or compatibility - you are never alone.<\/p>\n\n\n\n
