IC1318 Bi-Color (Summer 2015)

Full resolution image here.

The Ha [+NII] signal is overwelming in this area of the sky, but there is also prominent SII and some (less) OIII, so I mapped SII (and some OIII) to blue, Ha to red, and created a synthetic green channel to achieve this bi-color image.  The effect is to show Ha in red contrasted with the weaker SII signal.

IC 5070, or the Eye of the Pelican (8-2015)

Full resolution image here.

This is the northernmost part (north is to the right) of the Pelican Nebula.  I can spot six Herbig-Haro objects.  Compare my image with this one from NOAO.  How many can you find?

This is also first light with PHD2.  I like the new guiding program.  It measures guide star seeing in arcseconds, and it is easier to control.  It also remembers my setup.  Kudos.

B343 Fine, Summer 2015

Eighty-five percent resolution image here.

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.
