Description

To the wide field nebulosity captured with the RASA 8 under a recent moon lit night I added a bit of my Esprit data from 2019 to NGC1491. From what I can see on Aladin Sky Atlas (DSS2) there is not as much structure in the other nebulosities as in NGC1491 (Sh2-206), which I think looks like the face of a male wild boar with tusks. The lumps of nebulosity towards the top right are Sh2-205.
