Sky Conditions at Broemmelsiek

Sky Views from Broemmelsiek Park

Image on left is wide angle view in visible light. Image on right is IR image which essentially shows how much 'stuff' (clouds of water droplets or ice crystals, smoke, dust, etc) are up there interfering with views of the stars. Thus, we can distinguish between truly clear sky and "haze" (whatever its source). It is color coded, Black or Blue is best! See scale.

North is at the top. As the cameras are pointed straight up, we need to imagine that we are lying on our back with our head to the North and feet to the South to appreciate the camera view. The IR view is roughly 70 degrees N-S and 110 degrees E-W. The visible view is somewhat less than that.
