Description

This is a HaGB rendition of SH 2-173. Pixinsight does a nice job of color balancing that with the photometric color calibration process.

While I attempted to collect OIII data for this object, I now understand why this object almost never shows up as a SHO or HOO image. The OIII for this is very very faint.
