Altair Electronic Filter Wheel EFW 7 X 2inch XL

The Altair Electronic Filter Wheel EFW holds 7x 2" astronomy filters and is driven by a precision stepper motor with accurate positioning system. 

• Only 20mm thick! Note: Baader filters will not fit because they are too tall. Altair and most other filters fit perfectly. (Baader filters can be rehoused in blank cells to fit).
• USB Power - only one cable required for data and power!
• CNC machined from a single piece of aluminium. A light trap machined into halves to stop stray light entering the filter wheel housing. Motor is not exposed therefore light cannot enter through the gap between motor and housing.
• Supports interchangeable carousels amongst Altair XL size filter wheels.
• 7x36mm filter wheel and carousel include the required filter masks and screws to capture and hold 36mm unmounted filters precisely.
• Includes a set of adaptors and spacers enabling out of the box use with most astro cameras including the Altair Hypercam.
• Fits Altair Hypercam TEC tilt adjuster directly with screws, enabling a flush fit and 17.5mm spacing.
• M54 threads on the filter wheel body and screw holes for rigid connection. (See diagram).
• Included set of adaptors enabling connection to reducers and field flatteners with M48 or T2 male rear thread, with the required standard 55mm spacing to sensor.
• Includes screws and screwdriver, plus USB cable to get you started straight away.
• Please see the associated product images for fitment instructions and adaptor setup.
• Supported by all good astronomy capture software, such as SharpCap, NINA, APT, etc. Requires the Altair ACOM driver to work, which is downloaded at www.altairastro.help. Please note: You need to create a username to download the file.
