One cable operation

Filter Wheel requires a USB2 (TypeB) cable only. This simplifies the connectivity as it does not require a separate power supply when used with USB control.

Accurate Filter Selection

Carousel has seven (7) slots and accepts 2inch mounted or 50mm unmounted filters.

Filter Wheel rotates clock or counter clockwise direction for filter selection. A combination of a direct drive stepper motor and optical encoders ensure that your filter selection is precise, dead accurate on every filter location. Filter Wheel takes the shortest path when moving from one filter to another.

Thin Design

The body of the Indigo filter wheel is aluminium CNC milled. High quality aluminium alloy allowed us to design the filter wheel as thin as possible (19.0mm, 19.6mm with adapters installed on both sides).

Orientation on both adapters

Both sides of the filter wheel have M54 openings. The screw slide adapter (image below) allows you to properly allign the orientation of your camera or telescope side. Just untie the screws and rotate the adapter to the desired orientation.

Camera Connection

The 6 screw holes on the camera side allows direct connection with astronomical cameras that follow the same 6 x hole pattern (62mm diameter pattern). A neat feature allowing you to reduce the total backfocus instead of placing adapters.
