Hi,

you got some nice detail for just 1 sec exposures. 

Try keeping your histogram more to the middle, about 30% from the left and try also to not to blow out the core  when editing.

Use levels and curves gently and you'll get much better detail.

can you post the unprocessed stack?

welcome to sgl, good to see another brazilian here

I blowed the core to get the details around... but i'll try to fix it with the curves haha

[aleborek]

that was the unfinished, this one is the post stacking

Longer exposures will get better detail.

i'm having trouble with longer exposures.. no star tracker and it's a fight every night to find the southern pole hahaha but thanks for the advice

Aleborek,

you can try the darv method: http://www.cloudynights.com/page/articles/cat/articles/darv-drift-alignment-by-robert-vice-r2760
