Thanks for all the information, seems like there are lots of different stacking programs, just like scopes, that nearly cost me my sanity

. I haven't recovered from the research I did to find a scope. Like a said, I'm a bit of a quamby on a computer

, but I'm getting better. Not like I have much choice, considering everything that I use has something that needs me to use one

.
So to start with, I might have a look at IRIS, and being a true Dutchman, it's free, and once I get that under my belt, I might need something a bit more suited (should I get that far).
Thanks a lot for all the information that you have given me, I feel like I'm at the bottom of Mt. Everest in my Boardieswith my camera (I know how to use at least

). The journey begins.......
Regards, Dutch
