Crescent moon and Venus trails at twilight time

On 12/04/2024 09:33 pm by Tom Tan | Melbourne, Australia

I offer a trail of the moon progressively glowing from a crescent into earthshine plus Venus too.

This was the full frame without cropping.
I only had room for 9 shots within a 200mm frame because the moons were spaced at 4 minutes apart. I had picked a shutter speed of 1/60 second for the crescent moon and 4 seconds for the earthshine. With 9 stops, the moon was glowing brighter and brighter until the darker side started to show.

Tonight Venus was nearby. It was higher to the right. So I gave the left half to the moon and the right half to Venus. Those 4 dots of Venus belonged to the bottom 4 moons.

Nikon 80-200mm f/2.8 lens at 200mm and f/5.6 and manual focused
Nikon D750 full frame camera with 9 shots in one stop increment
tripod, no tracking (longest exposure at 4 seconds was okay)
remote shutter release, one shot every 4 minutes to leave a gap between the moons
compass

9 JPEG frames straight from the camera
9 frames merged as layers into one frame

No editing.

No boost to the exposure or contrast as I do not want to brighten the background sky.

I have chosen a range of 9 stops from 1/60 second to 4 seconds to show a crescent progressively turning into earthshine.

There was only room for 9 moons within the 200mm frame when they are spaced at 4 minutes apart and I also allowed some space in the first shot of the moon to let Venus just drop into the frame later on. The framing had to be precise to cover both
9 moons and 4 Venus. The trails were simulated and planned with Stellarium.
