NGC 3293 is probably the most beautiful open cluster in the skies.
It was planned to give NGC 3324 it's own imaging session and I didn't expect it to get entirely and so prominently into this field. The large field of the Riccardi-Honders and the large sensor of the PL29050 made it possible.
In Chile NGC 3324 is called the "Gabriela-Mistral-nebula" to honour the Vicuña-born poet and Nobel-price laureate; the nebula's outline resembles her prominent profile.
 
Narrowband-frames in Hα and OIII were added to the RGB-data to enhance the signal of the glowing gases in this star-forming region:

Combining narrowband-frames to a colour-image creates pictures with an aesthetic appeal of their own.
Following the modified bicolor technique by Steve Cannistra for combining Hα- and OIII-frames to create a synthetic green channel and especially Gerhard Wechselberger's Pixelmath-implementation in PixInsight I created a synthetic blue channel from the narrowband-channels. Combining them to a RGB-image while assigning Hα to red, OIII to green and the synthetic channel to blue created a colourful image with enhanced emission nebulae.

The narrowband images almost make it alone.
 
The Hα-image alone:

The delicate whisps of the ionized hydrogen are most prominent in this black and white redering.
 
And the OIII-image to round it up:

The mass of ionized oxygen-gas is a clear indicator that this star-forming has already produced several generations of stars. The heavy atoms were injected into the interstellar medium by titanic supernova-explosions, ripping the stars apart.
