This compact HII region is ionised by the B0.5 IV subgiant [F89b] S69 2. It is also a radio source and lies at the centre of a prominent infrared bubble. This is a faint and difficult object, made more challenging by the rainy weather we have had for the last couple of weeks. This image is 8.5 hours of exposure, with h-alpha data blended into the red and blue channels. Imaged on and off between September 23 and September 30, 2014. All the h-alpha was gathered during a waxing moon.
