Description

From Dataset from Roboscopes. 
It is an HaOIII image from 58 exposures (Hx12, Ox46) for 300" each = 4h 50m 
PixInsight : Dynamic narrowband combinations with PixelMath: 
R = Ha 
G = ((Oiii*Ha)^~(Oiii*Ha))*Ha + ~((Oiii*Ha)^~(Oiii*Ha))*Oiii 
B = Oiii 
-->BackgroundNeutralization.  
There were 4 spots in the RGB images (probably 52 Cyg ghost images): 
this disturbance is absent in Ha and OIII: also, the HaOIII combination 
looks better anyway, both for the visibility of the nebula and for its sharpness.
