I decided to [revisit ](https://macobservatory.com/narrowband-imaging-ic410-and-ic417/)IC 417 but this time with a wider field of view. The image was previously taken with my AT6RC, and it focused primarily on IC 417\. But this time I was able to frame it such that I also got the open cluster NGC 1907, as well as the smaller nebula below IC 417, NGC 1931\. I’m really happy with how it turned out.
