[Space] Images from Spacebridge Epsilon

I have a Fujifilm FinePix F30, which was supposed to be one of the  
better compact cameras for low-light photography in its day but is  
getting on a bit now. However, so far I have failed to find any  
hacked firmware for it.

One of the reasons the early FinePix cameras (especially the F30 and  
F31) had better low-light performance than their competitors was that  
Fuji resisted the urge to increase the number of pixels. The F30 has  
only 6MP. I believe more recent Fujifilm compacts have double the  
pixels but they automatically switch to a lower resolution in low light.

Are there any Canon cameras with larger CCDs or lower resolution that  
Spacebridge could use?
