Hi, Ken.
Can't really help you with the software you are using, but I think your focal length is too short.
I find with my homemade setup guiding manually, that 600mm f/l was needed to have any chance of making corrections.
At 135mm, what you are using, there is a 40 arc second tolerance.
At 600mm it's about 8 sec.
My guess is thats the problem.
There should be something in your help file that will tell you what you need.
Of coures it's just my guess.
Cheers,
Justin.
