I took more pictures of this object and added them to my previous session.

I think this is a little green, but I got backround quite dark..

 

I am still working to get flats right, but after testing I noticed that 50 frames without any calibrate frames gives me less noise.. And noise is the hardest to edit. Vigneting is easier..

I am going to make lightbox and I´m hoping to get opportunity to test it in this season, while nights are still dark.
