As much as i would like to sell you one, i would NOT recommend it for imaging only.
Planetary work, i would recommend.
Your main issue would be the resolution of your image. You really need more than 12 Bit A/D converter to get decent color and smoothness for DSO's etc. These cameras are 10 bit.
I recommend a Sony HAD sensor for any non cooled sensors. Noise is just so low, its amazing.
But for Guiding they are excellent, its just some use them as imagers because they could, but of course with its limitations.
Stick to the DSI Pro, as it has the Sony sensor, and has a better A/D converter and lower noise.
I have the data for it here
