CTA1 - a magnificent Supernova Remnant

Back home, this target is a tough one and I like a challenge. Based on Caltech first catalog (so the name of it CTA), this object named CTA1 looks like ... well … an hybrid between Alien (movie) and one of icons of Horizon Dawn Zero (I have a picture of Alloy at my place … such a great video game (so what ?? I’m fifty and I’m playing video game …)). It was supposed to be one of many nights to get more details … but unfortunately skies have been rough and I didn’t want to post before multiple nights shootings … but I only got one night and I’m finally posting it because I feel I will have to wait a long time for the next slot.
