September challenge up

Hi all,

This month's challenge is more an exercise in 'training your eyes' than a "shoot 'em up".

http://www.iceinspace.com.au/forum/s...ad.php?t=65405

The only way to train our eyes is to take time to 'see'. It is this experience that will allow an old dog's 50 year old eyes see a faint galaxy that a fresh set of 15 year old eyes can't, through the same scope.

One way to train up is by doing a sketch. Artistic ability is of no consequence. But when coupled with 'averted vision', it is a really powerful tool.

Averted vision refers to exploiting the most light sensitive region of our eyes- that area surrounding our central vision. It takes a little practice, but the sensitivity of this region of our eyes is remarkable. Shifting your eyes from an object and then, say, to half way across to the edge of the field of view, all of a sudden faint details become aparent. Look back at the object directly, and these features disappear.

The way to develop a sketch, start with some bright stars, marking their relative position, and then just continue the process.

The Challenge contains some suggestions on materials to use.

Have a go. Nothing to loose, and a universe to gain.
