Image description

Ain't that dark... the night? The city at night? No, the moon!

How come can there be illumination on its dark side? It is even visible with the naked eye.

For the same reason that we are able to see the observatory's shadow.

Even though it is not visible in the picture, the sun is truly the main actor of this scene,
producing the aurora and making the moon illuminated on both its sides.

Description of how this image was created

Not many technical points this time. The aurora is a photograph, the star field is not. All in all, a pretty simple shot to do, not much to say about it. I continue to use these new-for-this-round normal-based progressive transparency for smooth illumination effects.

The picture is tricky calibration-wise though. I hope it looks good on your monitor.

Comments by members when rating this image

1.	31-12-2009	A little too dark for my taste
2.	26-12-2009	It looks much better on my monitor with the gamma increased. [SMcA]
3.	22-12-2009	Excellent contrast, specially for a so difficult situation.
4.	21-12-2009	a good shot again, but the JPEG compression hurtede your image, so honnestly i can't see much
5.	18-12-2009	The moon and sky look good. I think the city needs to be closer to see a bit more detail, it just looks like some bright lines/pixels on my screen.
6.	17-12-2009	Only remark is that probably you won't find observatories in green, wet territories!
