The blue horsehead (IC 4592)
IC 4592 is a reflection nebula in Scorpius, sometimes named "the blue horsehead", that surprisingly is not photographed very often, as it's a beautiful and colorful object. It's also very large (relative to us), especially compared to it's cousin, the most popular Horsehead in Orion.
I have to credit my wife Ariana for being the one who came up with the framing of this object. I'm very happy she's the one who came up with it - I can't think of a better way to frame the "blue horsehead". Thanks Ariana!
As for the session, it was a very warm night at the DARC Observatory (average 70F), which forced me to cool the STL at "only" -5C. Despite I'm fighting a problem with the focal reducer, this image didn't turn out too bad. I was originally planning to add more RGB subs to get more accurate colors - yes the image is super colorful but the color data wasn't very detailed. In the end I decided to leave it as it is, and perhaps revisit this object next year.

You shall be proud of this beautyfull pic.
Best regards
As for the composition, as I mentioned in the comment about this image, my wife Ariana was the one who decided the framing of this image - we took a widefield image from the Internet of this area, drew a rectangle of the size of my field of view, then she moved it around, rotated it, etc. until she said: "there, this is how you should frame it". Now, every time I'm about to take a wide field of an area in the sky, I always ask her first :-)
