Selling my ST4 autoguider.
Great autoguiding unit, especially if you want to head out into the field.
I haven't used this system for a few years now, and she is going to waste sitting in my observatory. My new camera has a dedicated guide camera, so no need for this unit any more.
Comes with case. Case is handy to close over the unit to prevent dew.
Money goes to purchasing a rotating dome.
