The image is dominated by the central Breaking Wave Nebula spreading out from Gamma Cass to the Pacman nebula, but many more Sharpless nebula, clusters, and NGC objects are seen in great depth and resolution.
Each pane consists of approx 14hrs of LHaRGB data. Some frames have additional 03 data added in too.

Tom, that's an impressive and beautiful picture of the nebula caused by the ultraviolet flux and stellar wind of one of my favorite blue stars, Gamma Cassiopeiae.

Thank you!

I m delighted you like it.
With your username of 4725A, I m guessing you like Blue Stars like Gamma Cass.

Just like this meteor passing by the Pleiades captured in 2018 during the Perseid meteor shower. It was not until months after taking this frame at the Long Sault conservation area, outside Toronto, Canada, that I noticed it. Right at the edge of the picture. Maybe the stars are more distorted than I would prefer, or the noise could be lower. However, satisfaction cannot be measured by these quantities. It is about the quality of such Aha! moments that give life a purpose . Even if it was ignored for years or lasts a fraction of a second; like this meteor burning in the Earth’s atmosphere.


Find your shooting star!

Great picture, Iaffaldano!

Could you tell me the designation of the bright blue star at upper right?

If not, can you tell me the coordinates of your picture? And is north up?
