Question: when I try the North America nebula, stock Sony a6400, the stars are so bright that it obscures the beauty of the nebula itself although it is visible. You have such a strong contrast with the nebula vs the stars.
I’d that because of the L-Pro filter. Does the filter dim out the stars a bit to let nebulae shine?
The L-Pro filter only helps against light pollution and does not make the stars less bright.
The appearance of the image has to do with the processing. The first thing I do is separate the nebulae from the stars (with starnet++). This way i can boost the nebulae without making the stars brighter. At the end i put a little stretched layer with stars over the only-nebula layer and put them together.
I can tell you that it wasn't easy to edit the picture as it looks now. Without a modified camera, you probably have no chance of achieving a similar result.
