DSLR upgrade cools sensor for better astrophotography

hackaday.com

An old DSLR camera was modified with an external cooler to reduce sensor heat and improve astrophotography image quality. The upgrade uses a Peltier cooler attached to the sensor to combat thermal noise, which degrades images by introducing random pixel variations that obscure faint stars. This project aimed to enhance an existing DSLR for capturing the night sky, demonstrating a cost-effective alternative to specialized astrophotography cameras.
