A variety of "open" tools for optical and radio astronomy.
People in astronomy have been sharing electronics information for a long time.
Some people use a motor driver to point the telescope in the right location.
- main: cooling
Both radio and optical astronomy seems to work better when the receiver is cold.
- A Temperature Controlled Head Amplifier for 408MHz Radio Astronomy
- Peltier Cooler for DSLR. A temperature reduction of 12 'C apparently reduces the CCD dark current by a factor of 4.
- This Web Cam Autoguiding thread also mentions Peltier cooling
- "Noise Experiment #5: Peltier Cooler" describes more or les directly bolting a Peltier to the bottom of a DSLR camera.
- "DSLR Peltier Coolbox"
- "Is it more efficient to stack two Peltier modules or to set them side by side?"
- "Thermistor control of peltier voltage with Arduino (for DSLR chill box project)"
Someone over at the Bad Astronomy and Universe Today forum are considering using a wiki for FAQs and "a small library of the "Greatest Hits"".
Should I jump in and recommend one of the below astronomy wiki? I've been using wiki so long that I am a little disconcerted when a discussion forum has rules heavily discouraging editing even one's own posts, disparaging such edits as "revisionism". (But perhaps those people don't know about the "history" feature of most wiki). --DavidCary 22:55, 20 September 2007 (PDT)
