Starlight Xpress USB Filter Wheel with 5- Position 50.8mm Round/Unmounted Carousel (Female SCT/Male T-Mount)

Take your astrophotography and astronomy to the next level with the Starlight Xpress USB Filter Wheel. This configuration of the wheel features a 5-position carousel that accepts large 50.8mm round and unmounted filters that are ideal for use with large imaging sensors to ensure maximum light throughput so you can capture full-frame pictures without vignetting. This wheel is configured with a front female Schmidt-Cassegrain telescope (SCT) mount adapter so it can be securely attached to your telescope without the need for additional adapters so the back focus distance is minimized. On the rear of the wheel is a standard male T2 mount for attaching your photo gear.

Sub-miniature DC gear drives make quiet and vibration-free filter changes and each position is programmable within the control software that is available as a free download from the SX website. The wheel is also compatible with many popular third-party astronomy and imaging software such as AstroArt and MaximDL. The wheel is connected to a computer via a USB 2.0 port for software control and conveniently is powered by the USB cable. For those who don`t want to or can`t tether the wheel to a computer, there is an optional handbox control unit and independent power supply. Additionally, a standard serial port allows another computer control option, but power is not supplied, so a separate power supply will be needed.

If your rig or need changes, the front and rear adapters can be swapped for other optional mounting adapters and the carousel can be switched out for others that are available separately that accept different size filterseliminating the need to purchase an entirely new wheel. This is just the filter wheel and carousel; you need to provide the filters of your own choosing.
