If you are wondering where in Carina the Pulsar Jet of the Lighthouse Nebula is from APOD here

I have superimposed a Chandra image from here

This is my image with the Chandra image superimposed with Registar.

Great work Bert. I had no idea the Ha areas were so extensive around NGC3576.

Greg I just processed to show what signal was there. NII is far stronger than OIII.

Here is panel one unstretched as a compressed 16 bit tiff. I have only removed the gradients individually with PixInsight from the original fits stacks. Yes even with 3nm NB filters I get gradients due to the speed and field of the system.

This was just an exercise to see what was there.


I would be interested to see what anyone else can do with this data.

Nice widefield. A very interesting region in Carina chock-a-block with Ha/Nii.
