The Crescent in Ha and OIII #45444
Hi all,

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. All pointing, shooting, guiding, polar alignment etc done of course with KStars and Ekos. Processing, colour combination and background calibration done in AstroPixelProcessor, final touches in PixInsight.




Cheers, Wouter

Excellent! The crescent almost pops out of the screen! Where did you take it?

Thanks!!!

Ha was taken in my backyard in Spain some 30 km west of Madrid. OIII was taken at a very dark location in south eastern France.
