mmm, well, let me see, plugged that chip into CCD calculator (can handle that, handy if you bought one). Given a 1000mm FL, 9um pixel guess (which is a 342*342mm chip), to get a usefull 1.85arc sec image scale, with say a square 38000* 38000 pixel format, you get a 19 degree FOV.

mmm, that images the top ten nebs by themselves with a LOT of surrounding blank sky full of stars.

Nah, thats just uber wide feild wooze status. A 1.4 tera pixel (well, why not Peta pixel) chip on the other hand, would allow say 40 hrs on each filter just once, and youd catch everything in one go so you can spend the rest of you life seperately processing pretty much everything up there without ever taking another pic.
