SH2-232 H-alpha version RA = 05:42:30.0 DEC = +36:10:59.9 Exposures 31x900 sec Equipment Foto: TS ED-APO 90/500 mm cu QHY9M @-30°C Filter: Astrodon H-alfa 6 nm Ghuiding: Celestron 102/660 mm with Atik16ic, filter UHC Mount: EQ-6 Pro with EQMOD Stacking: DSS It seems to me that in the middle of this nebula there is a second one, it looks like a planetary nebula to me but I'm not the expert in this area. It is also visible on the image from the Nasa Sky Survey so is not sensor artifact or optical error
