Description

I tried to blend NB data (Ha, OIII and SII) taken with an AP 130mm GT + SBIG STT-8300M camera with data taken at the same time with HaLRGB data taken with a WO 81mm GT with an ASI1600MM-Cool camera.

The goal was to achieve some of the contrast of the NB with some subtle tone gradients while blending some RGB back to retain some star color and tame the rainbow look of the NB.
