Good question!! I am quite interested if anyone can give an answer. I have had to move to rigid coupler between my ZWO EAF and my Esprit100 because flexible couplers delivered with EAF are too much big and dont fit in the knob axis.

I reply myself. Saving master flat/master dark/master bias as xisf files it works. I have repeated image calibration/integration per two channels and I have repeated stacking process saving all masters (also master lights) in xisf format and no problem with star alignment process.

Hi to all, I am facing now the same problem as described in this post. I can not use star alignment process and I get the same error: Invalid conversion from byte vector type. I have tried directly saving all master fits files (L,R,G,B,Ha) into xisf files with command Save as, but when I try to carry out alignment with these xisf files I have no success and get the same error. You say that It is required to repeat the entire stacking saving all in xisf format, but as far as I know, this is not selectable. When image is integrated, this one appears in pixinsight screen directly in fits format (no option to select output format for integrated image). If I save it as xisf format, Am I not doing the same as I have tried, saving all masters as xisf at the end of the stacking? Do you maybe mean that when Lights are calibrated, Do I have to use master flat, master dark and master bias also in xisf format (now I have used these masters for lights calibration in fits format)? Any help is appreciated, because I am stuck and can not align my masters. Regards.
