i tried experimenting a bit more here, stacking in 'mosaic' mode might be a better option, from what i gather, i get more detail using maximun enthropy on nebs, but NOT for clusters and globs, i just use the median here- also, it seems bicubic for alignment is the best choice 'so far'- im not sure which calibration i prefer yet, but to tell you the truth, you WILL get a different final changing the parameters
