Lunar Iridescence

Tok, AK (Current Weather Conditions)

Caption: I was delighted to see iridescence in the clouds nearest the waning crescent moon.

As many of you know who shoot the moon, unless you shoot it zoomed in, set ISO, shutter and aperture to get detail, the moon will appear as a blob of light in the sky, like this, no matter what the lunar phase. This was yesterday morning before dawn, the moon was about... 35% and waning. Focus is set to infinity, exposure time is 13 seconds, f2.8, ISO 400. The date is indeed correct.

Lovely as always Katy. I certainly believe you are correct on the moon shots. I am not very smart, but I have taken many moon "blobs" in the sky.

I've lived in Alaska since 1969. I love this wild land. The extremes of the far north shape and affect every living thing. Extremes of weather, elevation, daylight hours, isolation, flora and fauna, nothing in Nature is insignificant.I have a Davis Vantage Pro weather station, uploading to Wunderground, (Turks on the Tundra) the National Weather Service, the Citizen Weather Observation Program and MADIS (Meteorological Assimilation Data Ingest System).
