Hi Everyone,

I wanted to get the color data before releasing this one but the forecast is for clouds throughout the next few days (hence my new Avatar!). Anyway, this is of the IC5146 (Cocoon Nebula) region done in Ha with a little red filter included to bring out the stars. I purposefully offset IC5146 so to show a portion of the dark nebula B168.

HaR 200:60 min

I think it will look cool when I get the color data. But until then....

Cheers,

Tom

Tom,
I realy like the framing on this image. IC5146 and B168 together make it look like the cocoon is moving through the star field and pushing away the stars.

The red filter is a neat idea. Are you blending the red with any kind of mask? I assume your intent is to bring out the fainter stars without bloating the bright ones.

That's a very nice image. I hope you don't mind my punching it up a bit in photoshop.

Great stuff Thomas..... really beautiful detail. I like Rolands "punched up" version too. It is hard to go wrong when processing such nice data.
