This is turning out to be a very informative thread. I had hoped so.
I wonder if there is any software or if script can be written where several guide exposures are taken over say 1-3 seconds and the least deviation from the last guide correction image is used to minimise fast seeing also.
So if you had multiple stars guiding and then multiple guide exposures and the least different exposure used as the actual most probable guide correction needed it possibly could improve results further.
It would assume a guide camera capable of taking 1 second or less and a mount where guide exposures of 3 seconds or more won't let the PE build up too much between corrections.
What guide exposure lengths are various members using for what mount?
I have found time and time again 1 second or less is best for my Tak NJP. I have been told you'll be chasing the seeing but I don't see that occurring unless on those really bad seeing days when you can see the correction amounts varying too much.
Greg.
