I like this nebulae and don't know much about it can anyone tell me where to find it in the sky and when ????

You can find it at constellation Sagittarius! From which place do you observe?
It is different from hemishere to hemishere even from country to country.
From instance, here in Greece i am able to observe Sagittarius only at summer..

Take o look here: http://en.wikipedia.org/wiki/Red_Spider_Nebula
It seems to be a difficult target, i wonder if we can watch it through a small telescope..
