Efficient Motor Design: Features a new motor with direct drive that reverses direction to take the shortest path between filters. This significantly reduces time spent changing filters during sessions, enhancing your imaging efficiency.
LED Indicator: Each filter position is uniquely indicated with a tricolor LED, providing visual confirmation of the filter change without the need to remove the wheel from the telescope. This feature ensures accuracy and convenience in filter positioning.
