Thanks,  Andy, Peter and Paul,

at the end of a nights’s session I can barely keep my eyes open and I have always taken a new set of flats and corresponding darks. I actually have a medical problem of not getting enough sleep which is getting to be a problem.  If I was simply imaging I would’t bother, but as I do a lot of photometry the flats may have been an issue.  I’ll try experimenting and see if there is any difference.  Peter’s experience seems promising.

Many thanks,
