I have the 70-200 f4L non IS, and wouldn't part with it. I toyed with the idea of the f2.8, but at the cost and weight opted for the f4, and have not looked back. For astro use it is amazing, and all I need now is the tripod collar which unfortunately Canon see fit to not include. A wonderful companion lens is the 17-40 f4 L.
