Have a little read through thread chaps.
It was a test really to get the band pass like Peter. The prom was not very bright Peter. You being so used to your aperture, but for a 60mm you need to do a separate run.
Anyway it was not meant to be one of my best images, just 30 seconds of data. No where near enough frames and no doubt the doubling is caused from using all the frames. Tomorrow maybe
