Warning: I used to save every blurry shot I took, now I delete almost all of them
For two years I kept every single frame from my back porch in Cleveland, even the smeared ones, because I thought stacking more would fix it. Then a guy at the local astronomy club showed me that 20 sharp shots beat 200 soft ones any night, so now I toss anything that isn't tight before I even open the stacking software. How many frames do you all keep from a typical session?
