1/3" CCD

I'm new to astro photography and have been using a little Vivitar 1/4 inch
color ccd camera with 'alright' results, but I want sharper images. I don't
have a lot of cash. But I found a 1/3 inch black and white ccd for about $50
on the web. It is the cvc 50 bc. It is a very small board camera sold as a
spy cam, but I'm thinking it might work well for astro photography.

Does anyone have any expierence with this camera?

How clear will details of planets be with a black and white camera?
