The Colour of the Moon

Our eyes don't really see colour at night, as our eyes are not adapted to nocturnal viewing. When we look at diffuse objects like M42 "Orion's Nebula" it appears as a gohstly grey/green. It's only when we image the object with CCDs or film that we cam see the beautiful colours of the object.
The same goes for the Moon - it may look big in the sky, but our eyes are our very own telephoto lenses and automatically enlarge the Moon for our brain.

This image was created by increasing the saturation of all colour channels in Photoshoppe, along with a bit of Gaussian blur to smooth out. A copy of the original image was desaturated and added as a luminance layer to save any highlight details that might be lost in the operation.

Taken with a small £100 refractor, there are two flaws (note to self!) -

* The image suffers from Violet Fringe (I forgot to insert the Minus Violet filter)
* The sky was cloudy, resulting in an image that looks blurred at the bottom!

Other Notes:
* Used Eyepeice projection to get a longer focal length, in this case the resulting
focal length was 3200mm @ f/40.
* Mirror lockup is a MUST, to prevent excess vibration as is a cable release

Did have some widefield shots of M45 (The Pleiades) as well as some of Jupiter and the Galilean moons, but ironically due to dead pixels and violet fringe on the brighter objects they're destined for the recycle bin!

[Update] Added these other to my flickr:
