Description

IC 1396/1396A is also known as The Elephant Trunk Nebula,  is an area of bright emission and dark nebulae located  2400 light-years away in the constellation of Cepheus. 

This image results from only 3  hours of narrowband data collected on October 13th - and is the first use of my portable Askar FRA400 platform for travel. It was also the first time I had to do PA when I could not see the northern portion of the sky.   The details of how I prepared the mount for travel and my use of the mount when I got to my destination can be seen here:

North Carolina is supposed to have good weather but that was not my experience on this trip.  After being there for three weeks, I only had a single evening clear and Moon free so that I could do some exposures!

The processing was a bit challenging on this project because of the short integration time and the fact that I ran into some guiding issues that caused elongated stars.   But all-in-all, it was a good learning exercise, and despite the problems with collection, I thought the image came out reasonably well. 

Full details on the capture and extensive processing notes for this image are available on my website at the link below:

Thanks for looking!

Description: I had a low color version and a high color version. My original posting was of the high-color version. I sent both images out on a Tweet to the Twitter #Astrophotography community and had them vote. The lower color version won out 2:1. I hate to give up on the rich blue color but in the end, I did roll back the saturations on the gold colors a bit. I like this one better.
