Elephant's Trunk in SHO

I forget the details, a couple hours in each channel, 5 minute exposures. I think I have a little extra in OIII to try and bring out that nice blue.

Nice! The many layers give a good sense of 3D.

Wow thank you for the picture.

Thanks! This is a good target for that effect. The framing is a little tight with my setup, but with a wider FOV I've seen this nebula look almost like a window into another universe, with the way that OIII region in the middle is set behind the darker dust clouds.

Wow. Great photo!
