What sort of tracking performance can you achieve?
I curious what sort of tracking performance folk achieve, particularly if they use permanently mounted gear.
Using a C9.25 (plus two other scopes) on a Vixen Atlux I check tracking by taking 3 seconds shots of a star - one minute apart for an hour or two and see how much drift occurs (with no guiding on the mount).
After PE correction I generally hope to see less than a stars diameter in drift over an hour- so for me that is about 12 arc seconds of drift an hour. What sort of tracking performance do folk experience here when their gear is set up well?
Many thanks,
Matthew
