Starlight Xpress Maxi USB Filterwheel 9x 50.8mm, M72 - M72 (56057)

The Starlight Xpress Maxi USB Filterwheel 9x 50.8mm, M72 - M72 is designed for astrophotographers who use larger format cameras and need a high-capacity, versatile filter wheel. It accommodates up to 9 round 2-inch (50.8mm) unmounted filters or 7 square 2-inch filters, with a large clear aperture of 65mm and M72 x 1mm threads for both input and output. The built-in off-axis guide assembly is compatible with many guide cameras, especially the Starlight Xpress Lodestar X2, making accurate guiding easy to achieve. The wheel supports multiple carousel options for different filter sizes and shapes, and unmounted filters can be up to 5mm thick.

The Maxi filter wheel uses the same control protocol as smaller SX wheels and can be powered and controlled via USB, eliminating the need for an external power supply. If using the serial input, a small battery is required. The standard output adaptor ring is a male M72 x 1mm thread, which is ideal for direct connection to cameras like the Trius SX-35 or SX-36.

This filter wheel is an excellent choice for advanced imaging setups that require a high filter capacity, large clear aperture, and reliable guiding integration with large format cameras.
