The filter wheel has five filter positions for standard thread 1.25" filters, to let you use your own imaging and light pollution filters. We particularly recommend the Astrodon and/or Schuler filters available separately on this website. A version of this CFW-9NF (#CFW9) is also available with four 1.25" SBIG filters – red, green, blue, and clear – at a price generally lower than the cost of buying the filter wheel and four RGBC filters separately.

The CFW-9NF system is designed to be “direct connected" to the Models ST-7/8/9/10/2000 imaging cameras for a thinner, more rigid mounting. An optional male-to-male T-thread adapter (#MMTC) is also available allowing easier (but less rigid) attachment and detachment for occasional imaging use. A variety of optional T-thread accessories are available for the front end of the CFW-9, including 1.25" and 2" diameter nosepieces, as well as a “Visual Back Adaptor" (#TVB) for direct connection to an SCT’s rear cell.

The CFW-9NF is operated through the CCDOPS software and utilizes a closed loop stepper motor system with positional accuracy of ±0.01" to switch between filters during imaging. The CFW-9NF adds approximately 1" of back focus.
