I've been away from here, for a bit, while I transition from IR and regular photography, back into Astrophotography, for the Winter. I recently purchased a new set of filters 3nm narrowband filters that narrow the bandwidth of the light that is transmitted through the telescope on to the CCD. Like Photo equipment, Astro equipment requires a lot of saving to get the good-stuff.
So this is my first image with one of these new 3nm filters. What you're looking at is Ionized hydrogen emission. I'm working on more data for a color image, but it requires a lot more time and the weather has not been cooperating.
This is an area about 2.5 x 3.8 degrees in Cygnus just East of Deneb. It required 3 nights to capture the data and has a total exposure time of about 7 hours. I thought folks might be interested in seeing a landscape of a different kind.

Thanks for looking and C&C are always welcome.
