Yes, autoguiding is using another camera (often with a separate scope) to tell the mount to move based on centering on a star.Hi Khalid,
thanks again for the good advices... Together with a USB-cam and PHD2 I got perfect autoguiding! Straight forward... and works very well with OnStep.
Shortly I took some pictures from Pleades... still quite poor seeing... and my photo-technique is still beginner level... however I'm very satisfied with the results. These are very small sections from original immage from center of immage... exposure time 220sec; ISO800; left without and right with autoguiding...
great thing! in both cases, polar alignment was the same and definitively not optimum...
