The Maxi filter wheel is ideal for use with larger format cameras, as it has the ability to carry up to 7 x 2-inch square filters, or 9 x 2-inch round filters. It also has a large input/output aperture of up to 65mm clear diameter (72mm x 1mm threads). The built-in off-axis guide assembly makes it easy to use with most guide cameras (Lodestar X2/Lodestar PRO or the Ultrastar/Ultrastar PRO are highly recommended).
The Maxi filter wheel uses the same control protocol as the smaller SX wheel and has both USB and serial inputs. The entire electronic assembly is USB powered and does not need an external power supply. (the serial input does require a small PP3 style battery, if this is used).
