I looked through all previous EGroup posts and sci.astro.ccd-imaging,
but was unable to find "final" details about this potential problem.
My GM-8 has been a flawless performer, and I am anticipating the
purchase of a CCD(STV)to be used primarily at f=650mm.
A few people have told me that the Losmandy stepper motors are a
constant tribulation due to the "torque-and-swing" action of the
stepper motors, and do not allow good imaging.
Some have said that in spite of good tracking accuracy, this sub-arc-
second swing constantly "smudges" the image.
Say it ain't so...
Thanks,
John
