Gina's Ultimate All Sky Camera
I'm hoping this is my final and hence "Ultimate" generation of all sky cameras. Based on the ASI185MC CMOS astro camera and Fujinon fish-eye lens of 1.4mm focal length and f1.8. Image capture is provided by a Raspberry Pi 3 in conjunction with INDI drivers. This is used with KStars/Ekos client software running on a Linux Mint desktop indoors. Communication is via Wi-Fi. The astro camera is an uncooled version but I have added a Peltier TEC cooler. This cools the camera down to something like -15°C for night sky imaging with longer exposures of around a minute. Daytime imaging is also covered using the camera's minimum exposure and gain. The colour camera differentiates between dark clouds and blue sky and also shows the colours of stars at night.
This Blog will describe the construction of the hardware and the special driver coding used to control dew heater, camera cooling and focussing.
