Really nice Mike. I know how faint these tendrils are. Below is a stack of 20 min exposures at 1600 ISO with the canon 5DH and Canon 300mm F2.8 at f/2.8 with an Astronomik 13nm HA filter. It is because of the obvious noise that I decided to build my fridge. I hope to do a mosaic in colour (for stars) and HA and O3 (for tendrils) of this region. I have also put your image on mine with Registar to show how vast this SNR is. My images show 7.0 x 4.7 degrees.

Again an image that really shows this faint region beautifully. Well worth any number of repro's.

I would have posted earlier but I had to hunt down this image from my archives.
