Description

The processing of this subject has been TERRIBLE because I had to fine-tune my APO and at the same time I was taking frames.
So I had one night with 0.1mm correction to the back focus, one night with 0.2mm correction ... and so on.

At last, I find the best back focus correction I was looking for and this will improve my next images (*) but this, unfortunately, is a mix of good and bad back focus distances and this reflected in distorted star profiles with serious chromatic effects along the border.

I used all the tricks I know to try minimizing the defect and this is the result, I'm quite happy maybe because I saw the first attempts! 

(*) not true, I have to start from the beginning because the backfocus ring I was using broke and I had to buy another one.
