Thanks very much for those links. I'll work my way through the 2nd one.

The FITS format has some weaknesses as a standard so you'll find there are issues with moving files between applications like CCDStack and PI. These can be resolved (PI has a lot of flexibility if you mess with the preferences) but it is generally more difficult to skip between applications.

I was using that but I must need to click on something as I could not get it to work. PI is no doubt a powerful program but its not user friendly which is a shame as that would really top it off.

I wonder if I have an earlier download I can use. I also notice the latest update of CCDstack 2 is bugged. It now often says it can't read files that it routinely used to.

Updating software is not always a step forward.
