Description

Rev A: 30s LRGB for the core 30:16:15:15

Rev B: just a few subs RGB, for the stars, before dawn broke 4:3:3x300s

Rev C: OIII and Ha, for the shell 12:6x300s

Rev D: all the previous blended together in PI.

The final blend was difficult, and still nowhere near perfect, as the core is saturated even at just 5 minute subs in the narrow band's, so getting the 30s core to blend into the 300s without blowing the tiny amount of detail I've gleaned has taken most of a day.

Haven't had a clear night since so no hope of matching Josh Smiths amazing 132 hours on this small but lovely PN. It's an ongoing WIP so hopefully more subs will follow.

Thanks to JulianR for showing me the Pixel maths way to blend the core into the shell, just need to do a better job now. Back to practising it.
