PixInsight Calibrating and Stacking Tutorial

• Very helpful: Pre-processing (Calibrating and Stacking) Images in PixInsight
• Prerequisite for PixInsight newbies: Introduction to PixInsight and its Interface

My Notes (from Processing NGC 4565)

De-Bayer

• The 60 flats are in /Volumes/Astronomy Data/2022 Targets/April 06 2022/NGC 4565/flat/. The first thing I did was De-Bayer them into flat-debayered.
• The 60 lights are in /Volumes/Astronomy Data/2022 Targets/April 06 2022/NGC 4565/light/. I De-Bayer them into light-debayered.

Integrate Master Flat

• Use the ImageIntegration process to make a master flat from the De-Bayered flats.

Calibrate

• Open the ImageCalibration process. Add the 60 De-Bayered lights and calibrate with the master flat.

Align (Register)

• Using the StarAlignment process (under ImageRegistration). I used image 5558 (from the middle of the series) as the reference.

Stack (Integrate)

• Use the ImageIntegration process to integrate the aligned images.

Adjust

• Stretch the images in PixInsight.
• Import into an ordinary image processing app (I used Apple Photos) to set black point, saturation, and color balance and apply sharpening.
