Maybe Luca Radice (Astroedo)'s "tutorial" is available outside PixInsight (if you don't have access to the latest PixInsight release)?Īnother very detailed paper on this topic was written by Craig Stark (" Profiling the Long-Exposure Performance of a Canon DSLR" ). Among other things, he discusses when the use of bias frames makes sense and when they are more likely to cause additional problems (with regard to CCD and CMOS sensors, amplifier glow, etc.), when dark frames should be used (calibrated and uncalibrated), dark flats, dark frame optimization etc. I would even call it an excellent tutorial on calibration in general. With the latest release of PixInsight (1.8.8-8 ) a very detailed and up-to-date description of the calibration process (ImageCalibration in PixInsight) by Luca Radice (Astroedo) appeared for the first time. I don't know if you are using PixInsight. In addition, you can find so many, sometimes divergent or even contradictory statements on the net on this subject. I currently use a Canon EOS 80D (CMOS) and calibration has always puzzled me. Thanks for bringing this one up.Ĭoincidentally, I have also been dealing with the calibration issue for quite some time. Hello, this is a very interesting topic, Taylor.
