Crescent Moon Rising in Alpenglow is a very delicate capture taken in Nautical Twilight over 40 minutes before Sunrise. The 3 percent crescent was barely discernible to the naked eye. This 3 second time exposure brought it right out though (sly smile). 😊

The single star showing through is about the last star I could see even straight up. It wasn’t a planet as it was twinkling away and planets don’t twinkle normally. You can see stars in Nautical Twilight but by the time Civil twilight rolls around (28 minutes before sunrise), the stars are long gone.

This is a classic rainbow Alpenglow gradient red orange yellow green blue indigo (ROYGBIV). I see these fairly regularly in the winter. It is not often I see them with clouds about. Typically they form in a clear sky gradient. Either way there has to be a LOT of atmospheric Ice for this gradient to form . A photographer has to be on his game not to wash this delicate color balance one way or the other.

Getting the entire outline of the moon even as a crescent is more common low in the mists I find out. I’m not sure of the physics of this but I think the reduced light from the moon minimized the dynamic range difference and allows the camera to see into the shadow a bit. Our modern cameras have amazing abilities but our eyes see differences in light dynamic range WAY better than the cameras do.
