Bubble shape formed by a star moving the nebula’s gas.

Lots of bad weather this summer so imaging bright objects that I know I can get good results.

Trying a hubble palette image this time. A little bit of oxygen component which helped to define the bubble.

Data collected on three nights. 12th & 15th & 24th August 2017.

Sii/ha/oiii image with 15 hours and 50 minutes of data. 19 x 20min Sii, 19 x 10min Ha, 19 x 20min Oiii 1×1 binning.
