Peltier Cooling
Today I finally got around to building a Peltier cooler for my Astro camera. The camera is an Orion deep-sky-colour, 11 model. I was shocked to discover just how much the cooler drew. At 12v it running at about 3-4amps much heavier power consumption than I initially thought the thing would draw.
My battery is rated at about 4amp hours, adding all the other elements I run it means that I will be needing an addition battery.
Understanding that many Astronomer's plays around with Peltier devices, how effective is the Peltier for Astrophotography? Is there any way to configure the device so it draws less current?
In addition, on the Uber-Highend Astro gear the ability to drop temp against ambient temp is cited, are these Uber devices using Peltiers or is there some sophisticated "Uber" Science? Any help in this matter will be accepted with gratitude.
