A reprocess from my image I posted last June. I processed the L-eNhance and Uv-Ir data seperately. I used ArcsinhStretch to stretch both to nonlinear. This helps to keep the stars colorful and tighter. Then combined both with Pixelmath. 60% L-eNhance to 40% Uv-Ir. I am really liking this method of stretching.
