Zodiacal light behind the iron curtain

http://i66.tinypic.com/2h5lawl.jpg
About 30 years ago people from Czech Republic, Slovakia, Poland and other countries could not travel without any problems. The biggest problem was iron curtain. Now we can travel around the world and see beautiful night sky but there is new big problem, light pollution. In this picture you can see remains of iron curtain, beutiful winter Milky way and Zodiacal light.
It is mozaic composed by 29 single pictures. This image was captured in Cizov, which is located in Podyji national park in Czech Republic.

I toke this picture in Dolomites Italy, on Feb 16th,about 5am. The milky way was hanging in the sky, and there are some mountains far away. The sun will rise up soon, so dawn is beginning to show in the east. The location i toke the picture is above 2000 meters, and there is some beautiful airglow in the air.

A ONE OF A KIND ECLIPSE COMPOSITE
A few nights ago, an idea hatched in my head. On a whim, I decided I was going to photograph the same region of the constellation Leo where last August's eclipse occurred. The purpose? Create a one-of-a-kind composite that rarely - if ever - gets published.
It wasn't a hard thing to do, actually. I would shoot a series of quick 30-second exposures for a two-pane stitch, then through Photoshop I would seamlessly (as much as possible) blend the eclipse shot from last August, into the final composite through layer blending and masking.
To do this, I shot a total of twenty 30-second exposures. Ten would comprise the top half, while another ten would comprise the lower half of the final image. Each was stacked separately in Deep Sky Stacker and manually blended in Adobe Photoshop in a process that brought this stout laptop to its knees. After that, I imported the coronal mask layers from the original composite from last August. After that, I then fine-tuned things up a bit, and then exported.
In short, it's a view - complete with the star Regulus and Nu Leonis (as well as dwarf galaxy Leo 1) - of the eclipse that one would've seen from outside Earth's atmosphere.
Image captured on August 21, 2017 with a Nikon D5500, coupled to a Meade Series 5000 80mm APO @f/6.

B33, LRGBHa with FSQ and ML16200 from Deep Sky West. Focused on "glow" in dusty area under the horse head silhouette. I imagine that area to be lit by the light of surrounding glowing red gases and glowing somewhat red itself. The shadow of he horse head is clearly visible below and to the left of the opaque silhouette. Sigma Orionis' impact is obvious. A lot going on in this favorite part of the sky!
