Assisted by the Light Vortex tutorial + after some wobbles, I successfully managed to integrate (stack) a set of LRGBHa subs for the first time, which looked OK when stretched. I've now moved onto the next step of alignment of the said images for subsequent combination in StarAlignment which on processing gives the the message:
*** Error: Variant::ToDouble(): Invalid conversion from ByteVector type
<* failed *>
Any thoughts on what's wrong?
I suspect the problem might be file type. On completing the aforemention stacking out of habit from DSS I thought I'd saved the finished stacks as Tiff files but I now see they were FITS - obvioulsy not paying attention. Strangely I can't see the output file typein settings but suspect that if it's still PI .xisf this could be a conflict? Below are the settings used and a full screen grab of the error.
