Any of the Canon G-series (<a href="%28http://tinyurl.com/27893kb"><b>http://tinyurl.com/27893kb</b></a>) is supposed to have the same *sized* sensor as the crop-sensor DSLRs.<br>The camera I've been coveting for this project is the Sigma DP2s (<b><a href="http://tinyurl.com/Sigma-DP2s">http://tinyurl.com/Sigma-DP2s</a></b>). The sigma has a built in intervalometer function in the stock firmware, and has a super awesome sensor that is supposed to work well in low-light situations (<a href="http://www.sigma-dp.com/DP2s/technology-sensorsize.html">http://www.sigma-dp.com/DP2s/technology-sensorsize.html</a>). <br>
Unfortunately the future of my employment status leaves me a bit trepidatious to spend much money on a new camera.<br><br><div class="gmail_quote">On Wed, Jul 7, 2010 at 4:39 PM, Charles Collicutt <span dir="ltr"><<a href="mailto:charles@collicutt.co.uk">charles@collicutt.co.uk</a>></span> wrote:<br>

However, so far I have failed to find any hacked firmware for it.<br>
<br>
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.<br>
<br>
Are there any Canon cameras with larger CCDs or lower resolution that Spacebridge could use?<div><div></div><div class="h5"><br>

I setup the cameras. They both auto-ISO'ed to 1600 which ended up looking like crap.<br>
The SD1100IS was the horizontal camera that took the super-grainy images, the vertical images taken by the A700 were less grainy, but still didn't get much visual definition. I like your idea of digitally removing the noise.<br>
I think if we programatically restrict to a maximum shutter speed of 1/4 we can get some acceptable images. I also think that we can get a lot better hi-ISO performance if we freeze the hell out of the cameras. Maybe a payload with two dedicated thermal chambers; one warm for the location/communication electronics, one cold for imaging apparati. The guys at NASA's re-entry watcher project (I can never remember their project's name) were saying something about there being a linear relationship between something like every 10º below 0 you can double the ISO, or something to that effect.<br>
I think the best thing would be just to get a camera with a better sensor.<br>

So who set up the camera? I there will certainty be some challenges<br>
and it is possible what we will need to do is fly a better camera. I<br>
would say we should set it up manually with a shutter of at least<br>
1/125 and the highest ISO that is low noise. ( We could look at tools<br>
that can build a noise profile for the CCD and remove it later too. )<br>
As for the aperture it might be that we can get away with a larger one<br>
I will try and run some experiments at shooting the sky with a large<br>
aperture.<br>
