At around 2:30, the telescope was slewed to the coordinates of BL Lac, which Stellarium had it at 28 altitude. However, when we slewed to its coordinates it was taking us much lower. We halted the motors at around 22 degrees as it was still going lower than that. Upon cross referencing other targets in stellarium, they seem to be around 5-8 degrees in altitude off from what is showing in sky6. The issue appears to have been that sky6 was reporting altitudes for targets an hour in the future, despite the control computer being at current time, as the altitudes appear to closely match Stellarium after the clock on the control computer was set back an hour (so the time on the control computer is an hour behind the current time). We are not sure when/why this happened or if its at all related to the upcoming daylight savings changes in a week from now.
