UBVRI filters are included with the filter wheel in this set.
The CFW9 is an automated five position 1.25" filter wheel. It is essentially the same size and shape as the former CFW8A to match the ST series camera body. They are difficult to tell apart by simply looking at them. When bolted to the front of an ST-7/8/9/10/2000 camera, the CFW9 and camera form an integrated system capable of automatically taking a sequence of several images through color, photometric or narrowband filters. The CFW9 gets its power and commands directly from the camera (a short cable plugs into the I2C port on any ST-7/8/9/10/2000 with USB electronics) so there is no extra power cable, communication cable or additional software needed for fully automatic operation. The same software that controls the camera also controls the filter wheel. The CFW9 has the same 1" backfocus requirement as the former CFW8A. It weighs less than one pound (14.7 oz). Please note, however, that since the CFW9 uses I2C port on USB cameras, it is not compatible with earlier model cameras with parallel electronics.
