Description

REV A: Single 600s Ha sub taken in the one gap that allowed it to be taken.

REV B: added 4x900s Ha and 3x900s OIII

REV C: Addressed balance issues which resulted in a new camera rotation to previous set. Thus a lot of my fov was lost in cropping. Unlikely to get to this again to replace the subs from the old rotation as a week of clouds has set in ...maybe next year.
I made a SHO with a false green and used the stars from that, to give the HOO stars some colour.
Definitely a target for better equipment and with a larger FOV, as VdB 152 lies very close to this object and would add some nice contrast.
