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.
Wow, I'm honored to receive such nice comments. I wasn't sure how an astro-image would be received here. I really love this type of photography, though the requirements and equipment are totally different. Here's a link to my set-up, if anyone is interested:
This target is not located well for me, currently. So I can only get a couple hours of imaging on it each night. Then it sets behind my neighbor's trees. But I plan to chase this one, as soon as the weather clears.
