      Description

      I`ve found the interesting article about this nebula https://arxiv.org/pdf/1810.01350.pdf.

      In the article in Chapter 4.2 you can see a description of multiple outer faint halo rings around the nebula. I was interested with that. I decided to take this nebula with a long exposure on a 40” telescope. The rings were worked out very well, also their centers are located close to the main star, but not exactly match with it. I represent the rings and their centers in the attachment.

      Rings scheme is shown below
