How to Modify Your DSLR for Astrophotography - Sky

- The main compromise involved in using a DSLR instead of a dedicated astronomical camera is temperature regulation. Cooling a camera makes a tremendous reduction in dark current noise, and many imagers will go to some lengths to cool their DSLR’s, or they'll purchase a DSLR that has a cooling unit installed as an after-market add-on. However, this may not be desirable to those who want to also use the camera for daytime photography, as it becomes too awkward.

- this would cool the inside of the camera down about 10C. since the inside of the camera was generally 10C above ambient when operating, the inside of the camera was around ambient. i did not build any kind of controller so the temperature was actually unregulated. that 10C made a big difference in the amount of thermal signal in my subs.

- You can cool a DSLR a little bit. A 4" computer fan blowing on the DSLR will cool a 6D about 4°C. Those "cold finger" setups cool it much more, but the problem I see is you will get dew or frost on the sensor. A dedicated AstroCamera will usually have a chamber with dessicant so the sensor is exposed to dry air (less chance of frost).

- By cooling the chip in this manner you can use longer shots without the worry of the chip heating up, thereby reducing thermal, shot and read noise all at the same time. With a DSLR we don’t have access to the chip so we will try the next best thing, cooling a camera. Reducing these noise sources lowers what they call the noise floor.

- Allow your DSLR to cool to ambient temp at least a half hour before imaging. Lower ISO means less electricity being pumped into the sensor, which produce lower temperatures. As was mentioned by rhart, different cameras have different sweet spots. In my experience taking short breaks between subs doesn't really help.

- The green line shows how the sensor heats up with no cooling (pre-modification, no copper attached yet). After just 20 minutes of imaging it's already 7°C hotter (roughly doubling the noise) and after half an hour it was still going up. The blue line is with the camera off and cooling at 80%. After 15 mins it is 22°C cooler that ambient - not bad.

- Cameras used in astrophotography are generally able to be used with exposure times ranging from milliseconds to hours. As your question stands, cooling the chip will have no effect on the length of the exposure time. What it can affect is the amount of noise in the image. Cooling the sensor generally reduces the amount of noise.

- Improve your DSLR astrophotography results with this "cold box" for your camera. Chills your DSLR camera's imaging sensor to significantly reduce unwanted thermal noise, resulting in all-around better images. Insulated and thermoelectrically cooled chamber chills your camera up to -43-degF from the ambient temperature.
