HDRComposition not work

[gianpri]

I've taken 5 series of photos of the M5 globular cluster, namely 5x60 ", 5x120", 5x180 ", 5x240" and 10x300". All the images are calibrated and aligned, all of them the same size and are in linear phase. Why does HDRComposition not work? Maybe it does not work on globular clusters? I used HDRComposition on M42 and everything worked perfectly.
Sorry my english, thank you

Hi John, start playing with binarize threshold, decrease it. This processing example may help. Saludos, Alejandro

Thanks Alejandro, it works but I had to decrease the binarize threshold up to 0.1400 !!!
