Hmmm... I have a little work around going at the moment, but I'd be happy if anyone can suggest a better way...
What I'm currently doing is this:
- Capture the spectra using K3ccdtools, etc
- Stack in Registax
- Rotate, crop, desaturate and save as a BMP in PS CS3 (because the spectrum is too wide for the Toucam so it has to fit diagonally, and rotate in Registax loses the star image)
- Open BMP in Registax and save as FITS
- Open image (one channel only as they are all the same) in VSpec
