    Here is NGC6751 done the same way as the Box , 5minISO1600 Canon Rebel T7i 'modified' 95xpwr 'Minus-Violet' PictureStyle Faithful-5200K' .
    I stacked them in MaximDL Pro as 'HfSz' ..Astrometric-Drizzle 90% and back to 100% size . After stacking I did "DoubleSize" and worked on it
    at that Bin1 size . "Local ASdaptive Filter to extreme values" , "FFT Filter Low-Pass User-Defined Radius 17 and Weight 50%" , "Curves -Luminance" got some extra brightness but when I tried the "Kernal Filter -Dilation3x3 with Pixel Restrictions for the
    lowest value to the highest value in the nebula it brightened it up but mainly if for Radius was at 10 and Feathering at 20 or more and then
    what looks like a dark lane became more visible . [ the Box Nebuladid the same but at Dilation5x5 with lower Radius and Feathering ].
    More magnification is needed here also .x
