There is a lot of argument that goes on between ST4 Guiding and Pulse Guiding. Most of the long term guys will tell you that pulse guiding is better but frankly I have had success with both. Pulse guiding does remove the cable from the system which in turn removes one possible problem from happening. I still have the tendency to use the ST4 cable but I always make sure to use the Auxiliary Mount in order for PHD to know which way the scope is pointing, thus saving me from having to re-calibrate every time I move the scope.
Thanks Sean, I did remove the ST4 and my guiding is 1,000x better. Still not where I would like it to be, but I haven’t had much in clear skies to playbaround.
i did want to offer some additional info that may help others, I live in the Los Angeles area, bottle class 8, perhaps this makes a difference in which option works better???? I have noticed in the past that when I was in a dark site, the ST4 method worked very well too. Thanks for your help.
Glad to help. Seeing conditions make a big impact on guiding. Learning to work those adjustments helps to. Run the guiding assistant all the way through and let it compensate for your backlash and it will really clean it up. Keep me posted.
