Hi! I've been struggling with this issue when processing my LRGB data and would like to figure out a solution for this. Here are my steps after stacking
- DBE on all RGB images
- Linear fit
- BlurXTer & NoiseXTer (optional)
- Combine RGB images
When combining my linear R,G,B images into a color image I got over saturated stars like the image attached here. However, if I stretch individual images before combing into the color image, the image looks fine. I'm puzzled by this because I've seen other Youtube videos where stretching if performed after combining RGB images. What am I doing wrong here?
- EdgeHD 8 with 0.7 reducer
- LRGB filters from Baader
- ~1h30' on each color (10s, 30s, 60s subs)
PS: A work around for me is just stretch individual colors then combine the RGB but doing that I wouldn't be able to use GeneralizeHyperbolicStretch (GHS) which I believe is great for stretching hard target like M42.
