Indigo Filter Wheel 7-Position for 2-inch Filters
The Indigo Filter Wheel integrates a 7-position carousel for 2-inch or 50mm unmounted filters into an exceptionally thin 19.0mm CNC-milled aluminum body. Power and control are handled by a single USB2 Type B cable, eliminating extra power supplies from your imaging train. A combination of a direct-drive stepper motor and optical encoders provides deadly accurate filter selection, moving to each position via the shortest possible path to minimize downtime between exposures.
7-Position Carousel: High-Precision Selection for 2-inch Filters
Designed for serious imagers, the carousel holds seven different 2-inch mounted or 50mm unmounted filters, enough for LRGB, narrowband SHO, and a photometric filter in a single configuration. The direct-drive stepper motor and optical encoders ensure the wheel lands on the precise filter center every time, rotating either clockwise or counter-clockwise. This system uses a shortest-path algorithm, automatically calculating the most efficient direction to move, saving critical seconds during an automated imaging sequence.
Ultra-Thin 19.0mm Profile: Minimal Back Focus Consumption
Every millimeter of back focus is critical. The Indigo Filter Wheel is engineered from high-quality CNC-milled aluminum, allowing for a main body thickness of only 19.0mm (19.6mm with adapters). This slim profile frees up valuable space in your imaging train for off-axis guiders, rotators, or adaptive optics, making it possible to achieve focus on systems with tight back focus requirements.
Single-Cable Simplicity: USB2 Power and Flexible M54/M42 Mounting
The Indigo Filter Wheel streamlines your setup by requiring only a single USB2 Type B cable for both power and data, reducing cable drag and potential snags. Both sides of the wheel feature M54 openings with innovative slide adapters, allowing you to loosen the screws and rotate your camera or telescope connection for perfect alignment. For direct camera attachment, the wheel includes a 6-hole pattern on a 62mm diameter circle, a 4-hole pattern for PlayerOne cameras, and a male M42 x 0.75mm thread, ensuring broad compatibility across many brands.

What filter sizes does the Indigo Filter Wheel accept?
The Indigo Filter Wheel has a 7-position carousel that accepts standard 2-inch mounted filters or 50mm unmounted filters. The maximum diameter for unmounted filters should not exceed 50.8mm.
How is the Indigo Filter Wheel powered?
It uses a single-cable solution. All power and data commands are handled through one USB2 (Type B) cable connected to your computer or control hub. No separate 12V DC power supply is required.
What is the exact back focus consumption of the Indigo Filter Wheel?
The main body of the filter wheel consumes only 19.0mm of back focus. When the M54 adapters are installed on both sides, the total thickness is 19.6mm.
How do I get perfect framing with my camera attached to the Indigo Filter Wheel?
Both the telescope and camera side M54 adapters feature a rotational slide design. You can slightly untie the retaining screws, rotate your camera to the desired orientation, and then tighten the screws to lock it in place. This allows for precise framing without unthreading your entire camera.
Can I use the Indigo Filter Wheel for a full LRGB and SHO narrowband imaging setup?
Yes. The 7-position carousel provides enough slots to house a full LRGB filter set (4 filters) and a full SHO narrowband set (3 filters) simultaneously. This allows you to switch between broadband and narrowband targets in a single night without opening the filter wheel.
Will the Indigo Filter Wheel connect directly to my PlayerOne camera?
Yes, the camera-side adapter includes a dedicated 4-hole mounting pattern designed for direct, secure connection to PlayerOne astronomical cameras, in addition to a more universal 6-hole pattern and standard M42 threads.
