Description

WR 134 is a Wolf-Rayet star in Cygnus, ionising an oxygen-rich bubble of gas which has been blown from its surface. This is set within relatively dense clouds of hydrogen.  WR-134 is the brightest star near the centre of the bubble.

I went as deep as I could with this one to pick up as much of the full circle of the bubble as I could, using nearly 30 hours of 20-minute exposures using a dual 5nm Ha / Oiii filter. Fortunately, this run of clear nights during July allowed me to capture this in 9 nights over an 11 day period.

The processing was done in Pixinsight, using a HOO-PIP rendering of the Ha and Oiii components.  The stars were replaced with a stack of 30s exposures using the L-Pro filter.
