This is data  on the Witch's Head nebula (NGC1909) combined from several runs on Pier 5 @Roboscopes in Spain (Tak Epsilon 180, ASI 2400MC Pro, Paramount MX unguided).

A 2 panel mosaic in OSC, Processed in PixInsight. Rigel just out of shot providing a lot of flare, but you can see how it illuminates the nebula. You can also see several small galaxies. Thes made the processing a bit more difficult as they needed to be carefully masked before stretching the main nebula (or clumsily masked depending on how well you think it worked).

Several of the galaxies are identified in this annotated version.

That's a great image 👍Considering Rigel is something like 40 light years away, it really shows what a powerful star it is.

Indeed it does.
