What was this red deep sky object? I was looking through sky yesterday and saw something red in sky (naked eye ) like nebula or something then tried using stellarium and mobile observatory apps to find out what it was, But couldnt find anything like this in them. I also tried to capture it on my phone but nothing visible except brightest stars.

I just know it was in cygnus - vulpecula - sagitta or somewhere near it.

As i wear glasses and dont have access to dark sky, it was my first naked eye view of some sort of deep sky object. Ill become so happy if i find what that red object was.
I think there are no deep sky objects (or extended objects) that show any color to the naked eye. They are too faint to activate the color sensors, so they appear white. I think you saw something nonastronomical. 

You will have a better idea the next time you see it; get a better estimate of its location so that you can find it on a star chart. Use binoculars if you have them.
