For DS imaging or do you want one for Solar System imaging?
Actually both DS and Solar system would benefit [/color] as the system reduces the effects of atomspheric seeing. It could turn a seeing night of 3 , which is just good to a seeing night of 5 , which is excellent.
I'm afraid that patents and general knowledge of companies doing AO maybe something that will make it really hard for others to overcome. Orion had some AO but right now it looks like they dropped those products, while SBIG or SX systems start at 1000-1500 EUR.
I am not aware of any intellectual property barriers regarding AO as most of the early research and development was funded by the US government and conducted at public universities. Regardless, it makes no sense to reinvent the wheel. The shortest path to success would be to work with SBIG ( diffraction limited.com) and develop an adapter that would retrofit their existing product offerings to work with the ZWO cameras. That way everyone wins.
