The Heart of The Heart Nebula (HOO Narrowband)
Firstly a bit of background. The Heart Nebula complex (Catalogued as IC1805 or Sharpless 2-190) is a large emission nebula revealing extensive amounts of glowing Hydrogen gas with darker dust lanes within. The nebula is found in Cassiopeia.
This strong red output and the entire nebula's shape is driven by the intense radiation of a small group of stars near the nebula's centre. This group is catalogued as Melotte 15.
This image captured in HOO narrowband (with a synthetic green component ) shows Melotte 15 (centre) with its associated knot of glowing Hydrogen gas clouds.
These clouds are sculpted into rope-like contorted, intricate shapes and whisp-like features due to the stellar winds and intense radiation, which is emanating from the young, hot stars of Melotte 15.
Dark dust clouds silhouette the image and the familiar dip giving the Heart nebula its name is visible upper left.
The image was acquired with an Esprit 120ED scope and a ZWO 1600MM cooled camera. Imaged on 14th/15th November.
40 x 300s Ha
20 x 300s OIII
All at gain 200 and camera cooled to -20
Ha mapped to red OIII mapped to blue and a synthetic green blend of both channels to green.
I also acquired some SII data and I may produce a Hubble palette version later.
Many thanks for looking!
