  • Notes:
This image was made after IC 348. Sometimes the mist from the valley would rise above the observing site, turning the sky hazy. Nevertheless, ten frames were good and clear enough to stack which yielded the images above.

The sky in the east during sunset. Notice the haze from the melting ice and snow.
