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.
