Description

I am very happy with the new telescope and have found that I can get detail in the cores of these PNs. The tiny core is done with short L exposures and HDR processing in PI. The main image is O-III mapped to the correct G&B values. The two are integrated in Photoshop with layers and masks. I could not find a good way to do it mathematically in PI.
