NGC7635 – Bubble Nebula in HSHO

Since my previous LRGB+HA image which can be seen here I managed to capture more data in the SII and OIII areas.  The bubble nebula has always fascinated me, it lies between 7100 and 11000 light years from Earth and is regarded as an Emission Nebula, inside the bubble there is a central star which is thought to be greating an expansion based on the massive mollecular cloud surrounding the star itself.

The data for this image was captured over a number of nights from the South East of the UK:
