The Green Ring Nebule  (Sharpless 3) Sh2-3

I adjusted the Gear and withdrew once, but after that there were few clouds looking up at the sky and stars appeared, so I took a picture for the first time in 2 weeks.
While waiting for the target time I was looking for, I took a picture of a strange nebula that I was pointing at the telescope. Hahahaha
There is a name called Green Ring Nebula, but I didn't mention it in the title because it would be fake because it doesn't appear at all. Can I pick it up if I take it with a G filter?
