Last Call of 2023: 89.5% Waning Gibbous Moon

Last Call of 2023: 89.5% Waning Gibbous Moon

And it is likely the last Moon I will photograph for 2024 unless some ideal conditions open up.

I was not planning on another Moon photo session this year, but being the weekend with an ultra clear sky, I did not want to pass this opportunity up.

One lesson I took from my Christmas editing fun last week is that a brighter exposure is better for lunar photography. Today’s image is a product of deliberately going faster on the shutter versus my more traditional speeds, which would be in the 1/2000-1/3000 second range for this current Moon phase.

If I do not write again Anno Domini Two Thousand and Twenty-Three, I hope you, dear reader, have a good weekend and turn toward the next calendar, and please be ready for more blog articles in 2024!
