The result of processing this data surprised me in terms of the detail and the way in which the false-color of red and blue narrow-band data creates a compelling rendition of this nebula! Two years elapsed between capturing this data and then processing it in 2018. I remember looking at the individual exposures and was blown away by the contrast of just a single frame.
The ironic beauty of this nebula is that it is created by the light from a star illuminating its own supernova remnants. Some 400,000 years ago the star ejected the now glowing-red regions of energized solar wind as it transitioned down to being a red giant.
NGC6888 is roughly 5,000 light years away from Earth. The data for this image was captured with an AT8RC telescope and QSI683WSG camera using Astrodon Narrow-Band filters, mounted on an Atlas EQ-G mount helped by a Lodestar X2 guide camera. The composition of the data was as follows:
Data capture was orchestrated by Sequence Generator Pro, guided by OpenPHD2 and later processed in PixInsight. See more info about this image on its Astrobin page, and read more about NGC6888 on wikipedia.
