Description

IC1396 is an open cluster in Cepheus associated with an extremely large region of faint nebulosity. One of them is the Elephant Trunk (van den Bergh 142) a star-forming region which is populated by several young stars (less than 100’000 years old). At the nose of the trunk lies Struve 2816, a triple star system that energize the nebulosity. This famous red area extends about 3 degrees in the sky and is very bright (mag. 3.5). It’s interesting to look at the dark lanes silhouetted against the dim glow : B365, the S-shaped one located northern, and B161 just under Struve 2816. According to last observations, IC1396 is about 3’000 light-year away from our home.

I was a little bit disappointed while processing the frames I took during a relatively clear night. The sky was quite good for my sub-urban observation’s spot, but I was expecting much more “red” signal. Finally I’m satisfied with the image and happy to have a new object in my collection.

Clear sky :-)

Description: Add 76 min of light frames during a 2nd session. Restart almost all processes under Pix from scratch. I tried to improve contrast and detail on the Elephant Trunk. Feedback are welcome ;-)

Description: I pay attention to global color and contrast, and also tried MaskedStretch for the 1st time. Goal was to obtain better non-linear stretched image than STF does.
