M63 the Sunflower Galaxy Canon Rebel T7i 'Baader Fringe Killer 2in. filter' 2.5XPwrMte 2960mmFL for 95xpwr' two 11minISO1600 RAWMono-Autosaves in MaximDL Pro V6.16 ' 152mm A+M Refractor(OfficinaStellare)' ' Auto-star matching - Sum' . I thought I did the same thing to both images .... and when I went to 'stack' them they wouldn't do it .?,~! ? . I then tried 'Manual 2 stars' to align them and I pressed 'GO' and it took awhile and they 'stacked' . I then did "Double Size" and it took awhile and then some commands would say ' Out of Memory ' so I wondered what was wrong . I checked both images and I forgot to "Half Size" the first one and that was being used as the 'Reference' image was at a Bin1 size and the second image was at a Bin2 size ...? but they 'stacked' . Maybe they will go together like in "ImagesPlus" where you can 'combine' different Format cameras to a one size image .? I don't know if MaximDL Pro will work that way for different camera types and sizes to become one image using ' Manual 2 stars ' aligning and if the 'Reference' image will determine the resulting image size ???? Checking the FITS Header for Pixel size will tell some of the result .z
