Just read a very in depth article over at hack-a-day about removing the IR filter from the Camera and adding a peltier cooler to keep the sensor cool during long exposures. You have to take apart your camera but thought some people might be interested...

| The Astros lost the World Series. Why would you want to photograph them? |

Lots of astrophotographers purchased Rebels solely because this modification is so easy to do. On astromart and other astro buy/sell sites, modified Rebels are available by the ton.
The Rebel is a very capable astro camera, as are may of Canon's other models. The 20Da was released in a factory-modified state. |

| I've heard of removing the IR filter before (although I haven't seen instructions this detailed before). The thing I found really fascinating that I hadn't heard before was the cooler. I know Nikons have been know to show purple banding if the sensor is on too long and it heats up. |
