Perfect — let’s build you a clean, reliable **multi‑night PixInsight workflow** tailored to your **RASA 8 + OSC G16 + LP filter** setup. This will give you a repeatable process you can run every time the weather finally cooperates.

# 🌌 Multi‑Night PixInsight Workflow (Optimized for Your Setup)
Your gear is fast, wide, and consistent — which means PixInsight can do a lot of the heavy lifting once you feed it clean, well‑organized data. Here’s a streamlined workflow that matches how you already operate.
# 🗂️ 1. Organize Your Nights
Keep each night separate:
```
M78/
Night1/
Lights/
Flats/
Darks/
Night2/
Lights/
Flats/
Darks/
Night3/
Lights/
Flats/
Darks/
This makes WBPP’s job easy and keeps calibration clean.
# ⚙️ 2. Run WBPP (WeightedBatchPreprocessing)
### Enable:
- **LocalNormalization**
- **CosmeticCorrection** (if needed)
- **Drizzle** (optional but helpful for RASA data)
### WBPP will:
- Calibrate each night
- Register all subs
- Normalize brightness differences
- Integrate everything into one master light
This step alone gives you a huge SNR boost from your multi‑night workflow.
# 🌙 3. DynamicCrop
Trim stacking edges and any drift between nights.
# 🌫️ 4. Background Removal
Your LP filter helps, but winter targets still get gradients.
### Use:
- **DBE (DynamicBackgroundExtraction)** for precision
- **ABE** if the field is simple
For M78’s faint dust, DBE is the safer choice.
# 🎨 5. Color Calibration
For OSC + LP filter, the best tool is:
- **SPCC (SpectrophotometricColorCalibration)**
It gives you accurate star colors and corrects any LP filter color shift.
# 🔇 6. Linear Noise Reduction
Your RASA at f/2 gathers a lot of signal quickly, but also a lot of sky noise.
Use:
- **NoiseXTerminator** (linear mode)
or
- **MultiscaleLinearTransform**
This step makes the stretch much cleaner.
# 📈 7. Stretching
Two good options:
### **MaskedStretch**
- Great for nebulae
- Preserves star color
### **HistogramTransformation**
- More control
- Good for targets with bright cores (e.g., Cone region)
# ⭐ 8. Star Management (Optional but powerful)
Winter fields are star‑dense. Your RASA makes beautiful stars, but sometimes they overwhelm the nebula.
Use:
- **StarXTerminator** to separate stars and nebula
- Process each separately
- Recombine with PixelMath
This gives you:
- Softer stars
- More contrast in the nebula
- Cleaner color
# 🔍 9. Detail Enhancement
Great tools for your three targets:
### **LocalHistogramEqualization**
- Enhances texture in the Fox Fur
- Brings out dust in M78
### **HDRMultiscaleTransform**
- Helps with bright cores
- Useful on the Cone region
### **CurvesTransformation**
- Final contrast
- Color balance
- Saturation control
# 🎯 10. Final Touches
- **SCNR** if green cast appears
- **Curves** for final color
- **Slight saturation boost**
- **NoiseXTerminator (nonlinear)** if needed
# 🌠 Why This Workflow Fits You Perfectly
You’ve built a small, automated observatory:
- RASA 8 at f/2
- OSC G16
- LP filter
- Multi‑night integrations
- NINA automation
- Plate solving
- Indoor control
This workflow extracts every bit of quality from that setup. Once the fog clears, you’ll be able to run this process like clockwork.
If you want, I can also build you:
- A **target‑specific workflow** (M78 vs. Monkey Head vs. Cone)
- A **framing guide** for your G16 sensor
- A **season‑by‑season imaging plan** for your west/south sky window
Just tell me which direction you want to go next.
