Beautiful and mysterious!
But "5900ly away,with an estimated size of 5100ly"?
Wouldn't that stretch across nearly 45 degrees of sky?

That is a very interesting area of the sky, Louie, and a really nice image too!

Hi Louis, great image. You've been busy...lucky you. By the way, how do you like the Starlight xpress? It obviously produces some nice images. I just picked up an H9C to give the platform a try, but alas I need to set up(more $$)a separate guide scope. What are you using as a guide scope?

Nice one Louie. There are some wispy threads of dust in it.
