Featured Photograph

Aurora Borealis from Haukland Beach

Composite sequence of the lunar eclipse on 8 November 2023. In the upper right the full moon is shown shortly after entering earth's penumbra at 1:11 AM. Shadowing of its western limb is not yet apparent. In the final image to the lower left the moon is in full umbral eclipse at 3:30 AM. Exit from eclipse was not captured due to low elevation over the San Francisco Peaks.

All images were captured at prime focus through a 10" f/6.3 Meade SCT with a modified Canon T5i camera. Exposures ranged from 1/1000s at ISO 100 to 1/25s at ISO 12800.
