Steve,
If I could make a suggestion; the scientific merit of this image would be enhanced if you also included (calibrated) Oiii data. (A mouse-over image that swaps the H alpha & Oiii would be instructive)
The distribution and ratio of these two gasses can be useful for inferring the relationship between the (gravitational) interaction of galaxies and the chemical evolution of their stellar populations.
What makes metal poor, dwarf irregular galaxies so interesting imho) is not so much their aesthetic appeal but rather the opportunity they give to observe the conditions which existed in most galaxies a long, long time ago.
best
