Hello.
In Demetra, when darks are added, i use the darks that best match the images. That is, if the spectrum has 60 seconds exposition, the darks i add to Demetra will last 60 seconds or so.
My question is, what about calibration and flat images? Those are only around 10 seconds. Should i add those images already calibrated with bias and darks? Or will Demetra not apply darks to those images? Or will Demetra apply the 60 seconds darks to them?
Thanks.
