Hi all,
I am building the darks library for my brand new 294MM and, as I don't think I'll have the chance to take any lights due to the preceptive cloudy weeks that follow the purchase (you know), I am wondering if there is any way to know the quality of the dark frames. I don't know if I have to measure the ADU, Read noise... All those concepts still seem a bit blurry to me.
Any clue would be much appreciated.
I've attached a single frame and the Master stacked with SiriL using the average method with Winsorized Sigma Clipping rejection, in case you want to have a look
