NGC 6888, also known as the Crescent Nebula, glows brilliantly in this wide-field image captured in RGB and hydrogen-alpha (Ha). The hydrogen emission dominates the surrounding region, revealing the intricate filaments and shock fronts generated by the powerful stellar winds of its central Wolf-Rayet star, WR 136. Surrounding the nebula is a faint OIII bubble envelope, adding an additional layer of depth and structure.

In this image, you can also spot the “Soap Bubble Nebula” (PN G75.5+1.7), a small, nearly perfect spherical shell discovered only a few years ago. It appears like a tiny soap bubble suspended in space, making it a unique feature within the same field of view.

Image Description and Details : Image taken with Meade LX8500 12" + QHY268m from Fregenal de la Sierra in Spain.
Ha 102x600" + OIII 102x600" + RGB for the stars. Total integration time of 49 hours processed in SHO palette.

Image Description and Details :

Part of the Cygnus constellation, the crescent nebula is located in the immediate vicinity of the star Sadr. Its atypical shape also gave it the name "Euro Sign Nebula" (currency).
On the left is visible the "Soap Bubble nebula", discovered only in 2007 by amateur astronomer Dave Jurasevich.
The image is a composition in the HOO palette, with an exposure time of 37 hours.
Setup DDM60 mount, Moravian G3-16200, Takahashi fsq85.
