could you comment on the accuracy of guiding required for shooting at 300mm focal length for 20-30min like you seem to do?
Does it absolutely require autoguiding?

Hi to All and thanks for commentin,

andyw, the guiding is very much needed here.
Depending resolution of imaging camera and given
focal lenght, it's easy to calculate pixels/archsecond.
In my case it's about 5pix/".
So unless you have a very good mount, some guiding is needed for maximal sharpness.
