Description

2-Panel mosaic widefield of the Jellyfish Monkey Head region; forty-eight 180 sec subs per panel.

Also contains NGC2175, NGC2129, NGC2158, NGC2175s, CR89, M35, LDN1564, LDN1565, Sh2-247, IC444, IC2157 IC2156.

OSC RGB natural color image with synthetic L. The region has a dense star field and to raise the visibility of the darker dust clouds a starless synthetic L channel was used to boost background structure brightness, then the usual star and halo reduction techniques and an application of PI's Exponential Transformation to raise the visibility of the main nebulae.
