Description

*** Was able to add data from 2017-07-29 to bring out the Oiii in the region as well as bring more definition and color to the Oiii envelope***

I finally had some clear nights and of course they were during an almost full moon. Despite the moon I just had to get out, so this was imaged over two nights with an average of 90% moon. I captured 1.75 hours of SII as well, but the signal is weak and with this limited integration all I could seem to do was neutralize color and add noise. I ended up settling on HOO as the signal was really good for both of these channels despite a short integration. I'm going to spend some more time on this if I get the chance. Dark skies would really make this target stand out.
