The Ghost of Cassiopeia -- OSC, Bortle 8

[Lee_P]

This was a tricky one! It's very faint, so I collected 16 hours of broadband data using an Optolong L-Quad Enhance, and then another 16 hours of Ha/OIII using my faithful Optolong L-Ultimate. Imaging details below the pic, and as ever more info is available on my website.
