Description

Yet another Iris Nebula ;) Actually I wanted to go for a huge Veil Nebula Mosaic but by the time I started imaging I realized that the Veil was completely behind a tree I didn't expect. Tired I just pulled the trigger on a target I knew was up and which I already prepared so I imaged the Iris on the two shortest and brightest nights of the year. Quite a tough job to get the dark parts of the nebula out without destroying the stars. However, this is another one in the series "been there before last year" and quite an improvement I think:

Let me know your thoughts :)
