B343 Fine, Summer 2015

B343 is an interesting patch of dust set against a background of glowing hydrogen in the constellation Cygnus.  Below the dark nebula and to the right lie ionization fronts formed in the hydrogen gas.  I think it's a pretty interesting area.

To the H-alpha set, which is used here as Luminance, I have added a night's worth of color with the SXVF-H9C.  The image looked better to me at 85% of original size, so no full resolution is posted.

I found a night in July for more time on B343.  Here is a complete H-alpha, full resolution image.

B343 in Cygnus (June 6, 2015)

70% resolution available here.

This dark nebula in Cygnus is here framed by the light of ionized hydrogen.  On the right are two brighter ionization fronts; obviously the cloud is moving somewhere.  Nearby small dark nebulae spot the area.

Usually, I present images full-frame, but parts of this area are dim enough that I was unable to get a clean image in 4.5 hours.  This image is shrunk to about 70% of full frame.
