Optimizing The Performance Of Your GSO Crayford Focuser
We inspect every single focuser before we ship it out to a customer. The performance is checked so you should not have to do this when you get a new focuser from us. However, with the passage of time and/or the load you place on your focuser, you will probably need to tweak your focuser a bit. At that time, the content of this article might be a very useful resource.
