Description

This AstroBin-first was discovered in 2010 by Sean Walker and Dennis di Cicco (as WD-1) and was later independently rediscovered by @Laurent_HUET in 2017.

Hu 3 is quite large - around 20 arcmin i diameter. The very weak and therefore previously overlooked Oiii signal has made it less likely that it is a true PN. It has no obvious CSPN.

Hu 3 has previsously been imaged in Ha by Sean Walker, but I believe this is the first ever colour image of Hu 3.

A Dynamic HOO palette was used. Image is Drizzled and heavily cropped.
