The Crescent Nebula in Ha and OIII

Post by wvreeven » Tue Nov 05, 2019 1:51 pm

The Crescent Nebula only in the light emitted by Hydrogen Alpha (red) and Oxygen III (green and blue). I took 48 subs of 600 sec each with a ZWO Ha filter and 127 subs of 180 sec each with a Baader OIII filter using a SkyWatcher Esprit 80ED and an ASI1600MM-C Pro. Processing, colour combination and background calibration done in AstroPixelProcessor, final touches in PixInsight.

its not only the crescent nebula. You also have pictured the soap bubble nebula. Look to the right above the crescend, in a diagonal line from the crescent to the edge of the image... the soap bubble nebula was only recently discovered by amateurs...
