  1. ZWO Optical: Manual 5-position 1.25"? Filter Wheel with a numbered “click” at every position to make the task a breeze.

    Changing filters couldn’t be simpler. Use the best MFW you can find on market!

    The ZWO manual filter wheel, designed to accommodate up to 5 31.75 mm diameter filters, attaches directly to the 31.75 mm tip of an eyepiece holder or to a T-type mount.

    It is compatible with all commercial CCD cameras and DSLR cameras: the connection with your imager is made either through the 31.75 mm tube (supplied with) adaptable to most CCD cameras (ZWO, Orion, Atik, SBIG, etc ...) or by using a T2 ring screwed on the 42 mm dia. 0.75 mm pitch, such as that fitted to Starlight Xpress cameras or digital SLR cameras.

    The movable turret (carousel) that can accommodate the 5 filters is manual and a click-stop system is heard when a filter is placed exactly opposite the imager, allowing a position rigorously identical to each rotation.

    The filter wheel housing is made of black anodized aluminum and is robust in design to support a CCD camera or SLR camera without any bending.

    Attention, filters sold separately.

  12. Atik Cameras: The EFW3 gives you more freedom and convenience to your imaging set up.

    For a large format wheel, the EFW3 boasts a slim, lightweight design. It measures 238×213mm dimensions and weighs in at just approx. 850g. This is great news for large format set ups where weight can be a real concern. That said, the wheel is fully compatible with any Atik camera when using the supplied M54 or M42 adaptors. We’ve simplified the technical side of the design from the EFW2 to further improve reliability and minimise component wear and tear. However, it's still machined from solid aluminium to produce a durable and quality wheel that will keep turning, night after night.

    Atik 16200 users will also be pleased to know that the EFW3 can either be attached directly to the camera as it is, or after removing the front plate to further minimise any backfocus requirements. With the front plate attached, the backfocus is 41.5mm, while the backfocus with the front plate removed is just 34.5mm.

    On the software side of things, the EFW3 has a full ASCOM driver, so any complaint software can be used to control it. Additionally the EFW3 can be controlled using our Artemis Capture software, for simple and efficient operation

  27. Flight Lakes Instrumentation: FLI High Speed Filter Wheel - 10 x 32mm filters

    High-performance servo motors featuring rare Earth magnets coupled with backlash-free power transfer provide ultimate torque which translates to ultimate speed. Adjacent filter distance is traveled in as fast as 23ms on the HS-625 model and 30ms on the HS-1025 and HS-1032 models, while the longest distance (180 degree wheel turn corresponding to three filter positions on the HS-625 and five positions on the HS-1025 and HS-1032) is covered in 45ms on the HS-625 model and 90ms on the HS-1025 and HS-1032 models.

    Control
    The control system not only optimizes the trajectory to result in maximum speed with minimum vibration, it also adapts to the changes in load. When filters are added or removed, the controller parameters must be adjusted in order to maintain peak performance. A built-in adaptation mechanism takes care of these adjustments providing optimum performance no matter what the operating conditions are.


    Servo Motor Advantage
    Encoder feedback sensors on the servo motors enable reliable operation compared to a stepper-motor-based open-loop motion system where step skipping may occur. However, the advantages of servo motors come at a cost of increased circuitry and controller complexity. This is addressed with state-of-the-art semiconductor components, a high-performance DSP (Digital Signal Processor), and a sophisticated control algorithm.

    High Speed Filter Wheel Features

    Wheel Design
    Weight-reduction features have been added to the wheel design for maximum speed. High accuracy and reliable operation is achieved by using custom designed components and precision machining. The filter wheel doubles as a pulley, reducing the number of parts necessary for efficient power transfer and maximizing the torque delivered by the motor.

    Deep Pocket for Filters    
    Filter pockets accommodate a wide selection of filters up to 9mm thick. The HS-1025 model holds up to ten filters with 25mm diameter, HS-1032 holds up to ten 32mm filters, and HS-625 holds up to six 25mm filters. Additional flexibility is provided by combining the HS-1032 wheel with optional 32mm-to-25mm adapters or other custom holders. The filters are secured in place by threaded retainers.
    Filter Access    
    Filter Access
    An oversized opening complemented by a threaded lid provide convenient access for filter replacement eliminating the need to disassemble the unit.
     
    Filter Position Indicator
    On the HS-1025 and HS-1032 models, the current filter selection as well as the position aligned with the filter replacement port is indicated through small openings near the wheel pivot. On the HS-625 model, the filter pocket index is visible when replacing the filters through the access port.
        
    Integrated Electronics
    All of the drive and control electronics facilitating the functionality of the HS-1025, HS-1032, and HS-625 models are contained in the filter wheel housing. This convenient solution eliminates the need for an external controller and the associated wiring hassles. It is still possible to operate multiple filter wheels through the same serial port by connecting them in daisy-chained mode. Simply connect a computer to the incoming port and a second wheel to the outgoing one to achieve functionality equivalent to a two-wheel system driven by a central control unit. Up to three filter wheels can be operated from the same serial port. Aside from motor drive and control circuitry, the integrated circuit board features a shutter controller allowing for a direct connection of a shutter without the need of external drive electronics.

A built-in adaptation mechanism takes care of these adjustments providing optimum performance no matter what the operating conditions are.


    Servo Motor Advantage
    Encoder feedback sensors on the servo motors enable reliable operation compared to a stepper-motor-based open-loop motion system where step skipping may occur. However, the advantages of servo motors come at a cost of increased circuitry and controller complexity. This is addressed with state-of-the-art semiconductor components, a high-performance DSP (Digital Signal Processor), and a sophisticated control algorithm.

    High Speed Filter Wheel Features

    Wheel Design
    Weight-reduction features have been added to the wheel design for maximum speed. High accuracy and reliable operation is achieved by using custom designed components and precision machining. The filter wheel doubles as a pulley, reducing the number of parts necessary for efficient power transfer and maximizing the torque delivered by the motor.

    Deep Pocket for Filters    
    Filter pockets accommodate a wide selection of filters up to 9mm thick. The HS-1025 model holds up to ten filters with 25mm diameter, HS-1032 holds up to ten 32mm filters, and HS-625 holds up to six 25mm filters. Additional flexibility is provided by combining the HS-1032 wheel with optional 32mm-to-25mm adapters or other custom holders. The filters are secured in place by threaded retainers.
    Filter Access    
    Filter Access
    An oversized opening complemented by a threaded lid provide convenient access for filter replacement eliminating the need to disassemble the unit.
     
    Filter Position Indicator
    On the HS-1025 and HS-1032 models, the current filter selection as well as the position aligned with the filter replacement port is indicated through small openings near the wheel pivot. On the HS-625 model, the filter pocket index is visible when replacing the filters through the access port.
        
    Integrated Electronics
    All of the drive and control electronics facilitating the functionality of the HS-1025, HS-1032, and HS-625 models are contained in the filter wheel housing. This convenient solution eliminates the need for an external controller and the associated wiring hassles. It is still possible to operate multiple filter wheels through the same serial port by connecting them in daisy-chained mode. Simply connect a computer to the incoming port and a second wheel to the outgoing one to achieve functionality equivalent to a two-wheel system driven by a central control unit. Up to three filter wheels can be operated from the same serial port. Aside from motor drive and control circuitry, the integrated circuit board features a shutter controller allowing for a direct connection of a shutter without the need of external drive electronics.

  29. Flight Lakes Instrumentation: FLI High Speed Filter Wheel - 6 x 25mm filters

    High-performance servo motors featuring rare Earth magnets coupled with backlash-free power transfer provide ultimate torque which translates to ultimate speed. Adjacent filter distance is traveled in as fast as 23ms on the HS-625 model and 30ms on the HS-1025 and HS-1032 models, while the longest distance (180 degree wheel turn corresponding to three filter positions on the HS-625 and five positions on the HS-1025 and HS-1032) is covered in 45ms on the HS-625 model and 90ms on the HS-1025 and HS-1032 models.

  30. Flight Lakes Instrumentation: FLI Twenty Position Dual Color Filter Wheel (for 25mm diameter filters)

    Color Filter Wheels
    Our color filter wheel’s robust mechanical design provides the basis for stunning, uncompromising images. Each FLI color filter wheel is precision engineered with a highly accurate no-slip drive chain and stepper motor. The large diameter pivot pin and bushings are precision ground and matched for smooth, quiet no-fuss operation night after night. FLI color filter wheels do not use internal lights for homing, so your images are protected from stray light interference.

    FLI's proprietary Zero Tilt Adapter (ZTA™)
    The ZTA™ is an FLI adapter design that eliminates the common deficiencies found in most astronomical adapters. When you use the ZTA™ you will never experience tilted components, marred adapters, or wobbly interfaces!
     
    The ZTA™ adapter system employs a circular spring that evenly distributes the pressure of three set screws against the ZTA™ dovetailed surface. The resulting clamping force between the two machined surfaces results in zero tilt, zero adapter marring and a complete elimination of problems associated with loose connections. The ZTA™ adapter can be machined to fit nearly any type of camera, color filter wheel or telescope.

  31. Flight Lakes Instrumentation: FLI Ten Position Dual Color Filter Wheel (for 50mm square filters)

    The FLI CenterLine color filter wheels feature a centrally located aperture that presents a symmetrical mass distribution and eliminates the offset weight problems associated with virtually every other color filter wheel on the market. It is also ideal for prime focus installations where a zero or symmetric shading of the primary mirror is critical. The CL1-10 CFW presents an easier load to handle vs. a normal color filter wheel and it will not change a telescope's balance as it tracks across the sky. The FLI CenterLine also allows for filter combinations unavailable with traditional style filter wheels.

    The first FLI CenterLine to be released is the model CL1-10 which holds up to ten 50mm x 50mm square filters in two independently operated wheels. It is powered by two internally mounted stepper motors and two TruMotion synchronous belts. The internal wheels are supported by radial ball bearings that provide a smooth, quiet and repeatable operation.

  32. Flight Lakes Instrumentation: FLI 5 Position Color Filter Wheel (for 2" or 50mm diameter filters)

    At less than 7/8 of an inch thick, the CFW-1 color filter wheel is designed to closely and rigidly couple to any CCD camera. The homing device of the CFW is highly accurate and repeatable. The recessed opening of the color filter wheel securely clamps to an IMG, MaxCam, or "AD" adapter mounting flange. This setup adds a minimum distance to the light path and avoids the vignetting issues common with other designs.

    The T-mount system was introduced by Tamron in 1957 as a universal lens mount for 35mm cameras. The idea was that each lens would have a standard threaded rear flange. A camera specific adapter would then be attached at the point of sale, as needed. This greatly reduced costs since only the T-mount adapters needed to be stocked, rather than different versions of every lens.

    With T-mounts readily available for most camera bodies, it was natural for astronomy buffs to settle on it as the standard adapter for 35mm astrophotography. Without this inexpensive and easy to use adapter, astrophotography might have gotten off to a far slower start than it did. On the downside, the T-mount was designed to solve a very specific optical coupling problem in 35mm cameras. Progress in telescope design and CCD array size is revealing the T-mount as a potential bottleneck in the light path.
