Last evening, I catched the young, crescent Moon:

Photographed through a telescope with a focal length of 1085mm at F/7.

 

Leica M9

Visoflex III

4 sec.

ISO 320

 

Some starts are visible also.

 

The question of the day is: The bright crescent is illuminated by the Sun. Who has an idea where the light comes from which is responsible that we see the 'dark side of the Moon'? ;)

Earthlight, i.e. seen from the dark side of the moon the Earth is still close to "full" and is very (VERY) bright, thereby lighting up the dark side of the moon. But I think you already knew that.

 

For me the crescent is too bright, or lacks detail being a blown highlight. I guess you could expose for that and then adjust in PP. I think this would give some detail in the highlight. You still seem to have plenty of dynamic range available if using ISO 320.

 

Anyway all in all a very impressive image. Nice to see what you can do with a visoflex & M9.

Thank you for your comments, guys!

 

Indeed, its reflected sunlight from the Earth, which is illuminating the dark side of the Moon. Depending on the situation on Earth (clouds, more ocean or more continents), it is more or less bright. Sounds consequential that the phenomen is called 'Earthshine'.

The photographer has to decide, which part of the Moon he want to optimize the exposure for. Because the difference between the crescent and the earthshine is exceptional high, it is not possible to have both. Even with HDR it is *not* possible without loosing a natural look.

 

The following image is done just 8 minutes before the first one:

The exposure time is only 1/60 second at ISO 200, 8,5 EV less compared to the first image.
