You can use any third-party software that supports the ASCOM Focuser standard, or you can use FocusPal from Shoestring Astronomy. It is a stand-alone program that allows you to control the speed of your focus motor, and to run the motor in and out. It is free and can be downloaded using the link found below. Even if you plan on using third-party software, you should download and install FocusPal to verify that your FCUSB, computer, and focus motor are all working properly together. If your system works fine with FocusPal, but not with your third-party software, then the problem most likely lies with the third-party software and you should contact them for technical support. If your system does not work with FocusPal, then you should contact us for technical support."; function tShowHide(id, show) { var s = document.getElementById("desc"); if ((s.innerHTML.length<=212 || show==1) && show!=2) { s.innerHTML = fDesc[id]; if (document.getElementById('m1')) document.getElementById('m1').style.display='none'; if (document.getElementById('m2')) document.getElementById('m2').style.display='none'; if (document.getElementById('more_txt')) document.getElementById('more_txt').style.display='inline'; } else { s.innerHTML = ''; } }
