Last night I setup the GSO RC12 with my STL11K and proceeded to image the Trifid. What I found disturbed me in that my normal guide settings did not work well with a focal length of 2400mm. I initially had aggression set at 4 for each X and Y. I went down as low as 3 on each but the guiding was all over the graph and in fact going above and below. I then changed the movement jumps from 2 pixels maximum to 1.3 in each and still no improvement. Finally I went back to the default settings with aggression set to 10 and this gave a marginal improvement.
All this through the internal guide chip. Is this normal? Will using a MOAG improve the situation?
I would really like to nail this problem down. Anyone got any suggestions? I am all ears.
