Description

It has been about a year since I did my last image and although I wanted to play with my QHY247C camera I decided to "retrain" by taking another narrowband image of a target I had gotten partially before with the FC100DF (i.e., IC1396A or the Elephant's Trunk region of IC1396).

This image was a national (US) finalist in the 2019 Wiki Science Competition in the General category:
