Description

A relatively deep image of the Iris Nebula which is nicely framed by the TEC140/QSI690. The surrounding dust was quite hard to drag out with the relatively slow focal ratio. After calibrating the colour I observed a pinkish flare around the central star which I have preserved in the final image, though I am not sure if this is real or a processing artefact.

I am slowly catching up on my processing backlog ;-)
