What are the minimum/maximum temperatures in which my instrument can operate?

Our instruments are designed for use between 0°C and 40°C. With negative temperatures, our instruments may still work, without risk of damage, but :
  1. The quality of tracking may be affected, resulting in finer, rounder stars.
  2. The battery may be drained faster due to the cold and the usage of the heating dew system.
