Hi .
For the first ti e I learn wbpp stacking with kew words using Adam block method .
But as you see the picture below low ha brighter line across like 1/4th of image
Any idea if is calibrating problem or else
I had three nights to take I between the nights I moved the Camera by mistake as it was loose and the frame got changed then I had to take ne flats but some how went wrong on stacking .
Give me your thoughts please!
