Sometimes I like to see an area of sky without none DSO, with only stars, and appreciate the dispositon of them. See some shapes like arrow, semi-circle, sine wave they are.
My goal with astrophotos is to know the sky, see what I can't see with nude eyes. All cluster were nebulas. Big or small one. They have the history of the Universe much time ago. Some little globular cluster have the same age of Milk Way. See them is see the past of the Universe !
note: all them in constellation of Vela, near of Eta Carina nebula !
