Hi All here my latest tutorial: as from the subject it's about using an H alpha image to enhance HII regions in spiral galaxies.

The method is directly derived from Vicent Peris formula for composition of Narrow band data with broad band ones.

I how you will enjoy

Hi Edoardo

Thanks for your extensive tutorial. It's great.
Should that work on nebulas as well? If so - is there any way to incorporate OIII in the same manner to preserve color calibration?

Best

Hi, Thank YOU for reading!

This Tutorial is thought to work mainly with object with mixed continuum and narrowband emission like galaxies.
Nebulas are mainly narrowband line emission.
It can work, but it is not suited for it.

Much better is the Vicent Peris article here

I don't know if this method can work with OIII emission: OIII is a mix of green and blue, so, maybe we can try to apply the method to both the channels and try to enhance the green and the blue component...

but I've never done, it would be very interesting  ;)
