As Seen on ABC TV ” Stargazing Live”!

This image was featured on “Stargazing Live”. When noted panellist, Prof. Brian Cox was asked about the image here, he said he hadn’t seen this DSO before!

Pretty cool to show someone as well informed as Brian Cox (whom I respect enormously) something new.

This was originally very difficult to process with the moon and gradients, but the new version was done with Startools, which is an awesome App. It has amazing built in gradient removing functions, amongst many others including deconvolution, wavelet sharpening, star reduction and phenomenal noise reduction algorythms built in. Highly recommended!

About this Nebula

Why is the Lobster Nebula forming some of the most massive stars known? No one is yet sure. Cataloged as NGC 6357, the Lobster Nebula houses the open star cluster Pismis 24 near its centre – a home to unusually bright and massive stars. The overall blue glow near the inner star forming region results from the emission of ionized hydrogen gas. The surrounding nebula, featured here, holds a complex tapestry of gas, dark dust, stars still forming, and newly born stars. The intricate patterns are caused by complex interactions between interstellar winds, radiation pressures, magnetic fields, and gravity. NGC 6357 spans about 400 light years and lies about 8,000 light years away toward the constellation of the Scorpion.
