Antennae Galaxy NGC4039 at 95xpwr magn. with a Canon EOSII Rebel T7i modified-Hutech for 11minISO1600 images...image is fourTIFF's Sum stacked in MaximDL Pro V6.16 . I used "Kernal Filter - Dilation7x7 with Pixel-Restrictions" for the glow around the galaxy two times on each image before stacking them and then another three time after that ... the glow seems more evident but I don't know how close to reality the look of it is . Jupiter at 95xpwr with a ZWOASI120MC-S WebCam shows a dark spot that is the IO shadow and in the top right area of Jupiter it looks like IO can be seen as a white round bump .x
