Here is a good setup for someone with a mono ST series ccd.

CFW8 filter wheel Color Filter Wheel for ST-7/8/9/10/2000 cameras that have USB electronics. This filter wheel holds up to five 1.25" filters - Red, Green, Blue, Clear and Nebular filters are included in this package. Plugs into CFW/AO/Mount port on the camera and provides and RJ11 socket for guiding - leaves you the I2C free for other equipment.

also

Muscle plate (replaces thin SBIG original and stops flexure)
Adapter/Spacer to allow use with an AO-8.

I am looking for $500 plus postage for the package.

PM me if interested - I can email you photos of and taken with this wheel if desired.
