This is a basic, manual filter setup. The 2 in. Astronomik filters are parafocal; they are dichroic and have IR blocking. Each will come with its separate drawer that fits into the holder. The holder has a T-thread on each side (one male and one female); so it can be fitted to pretty much any CCD camera. I have a T-thread to 2 in. (.24mm) connector that I used with my Apogee camera. There are other adapters available to fit any other camera (SBIG, Starlight Xpress, etc.). Everything is in pristine shape. Check out the Adirondack site for more information.
This was purchased new for a total of 655.00. Will sell for 485.00 shipped. I prefer to sell this as a unit but would consider selling the filters separately if necessary.
