I recently became highly interested in deepsky astrophotography and I felt lucky finding this platform.
In my post-processing workflow in PixInsight 1.8, I found myself very confused in the Image Calibration process.
The annexed image is an example. With the master calibration files downloaded from googledrive, I used ordinary parameters to calibrate the light. But when I inspect the calibrated light, I found that no hot noise pixel was subtracted but the calibrated light was even more noisier than the uncalibrated one.
Am I using wrong parameters, or am I using wrong calibration file?
I remember that the auto-calibrated lights from the platform obviously were cleaner.
Much appreciate for your helps.
