About this image


NGC1491 is an emission nebula about 10,700 light-years distant. The 11th magnitude star in the center seems to be energizing the region and also forming a type of blister formation. Also note the waterfall like structure at around 11:00 o.c. that also shows strongly in OIII.

This narrowband image was processed in the standard Hubble palette.
