About this image

I'm still not happy with the processing for this object. At the time I was suffering from opacification of my lens implants and so lost colour and contrast. Consequently everything I processed was overcooked. Later, after the implants were replaced I could see the errors and reworked this image. I may have over-compensated.

I've had to reduce the size of this image to 50% to fit within the 2Mb limit.

This region is an open star cluster in its formative years. Here we find red glowing regions where stars are being born, dull red regions of hydrogen emitting its characteristic red glow and blue reflection nebulae, where light is being scattered from fine particles, like sunlight is scattered by air molecules in the sky. We also see dark streaks, which are areas of dust which absorbs the light from the brighter objects behind.

Over time the gas and dust will be swept away from the new stars being formed here, and what remains will be an open star cluster.

This region is thought to be about 2400 light years away. It was discovered on 16 Oct 1784 by William Herschel, who entered the central part here in his New General Catalog: NGC 2170.
