Witch Head Nebula in Orion (HaRGB)

A faint reflection nebula depicting a fairytale-like crone, hence its name.
The nebula, formally known as IC2118, is associated to the nearby star Rigel, in the constellation Orion.
Its distance from Earth is approx. 900 L/Y.

Shot under Bortle 3 desert skies, Israel

WitchHead HaOiiiRGB Final web

29*300 sec RGB
12*600 sec Ha extract (L-eXtreme)
ZWO 2600 MC Pro
ASIAIR Pro
iOptron CEM25P
ZWO 120 MMs Mono

Used the Ha-Oiii - Ha extract for the OSC stack with the L-eXtreme
Such a great feature.
I combined also the Oiii data in PIXI but, that was too faint for any real difference.

Whoops, didn't mention, the WO RedCat51.
(A lovely recent addition to my wide range optics).

Thank you!

I was lacking more data in RGB imo.
For some reason I had to throw around 6 frames or so, from the start of the RGB session.
I started with the Ha(L-eX) because the Moon was up, and no trouble there, all 12*600sec were perfect.
