Smaller than SH2-86, this object has same kind of shape but is smaller and fainter than SH2-86. The hydrogen-alpha filter works very well with this object and the wider field of view will pick up some of the fainter clouds around it. A larger telescope should easily pick up nice structure this object has within it. The RGB came out very weak so you need quite a bit of it to make a nice HA-RGB image. I took a 15 minute image with the oxygen III filter and picked up nothing, so I do not this is a good target for narrowband color.

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.
