Astrophotography by Dariusz Krzempek
At some point while using the controller, I noticed that the ESC button wasn’t always working. I lived with it, but after a while, the left Ra button also started acting up and wouldn’t always connect. A red flag went up in my head – something needed to be done. It’s worth noting that the problems appeared right after the warranty period ended… coincidence?
The GOTO controller is extremely convenient and practical to use, when you want to look at interesting night sky objects, with your own eye through the eyepiece mounted in the telescope’s focuser. The ability to quickly select an object using the GOTO controller, is invaluable.
