Description

Imaging Air Cherenkov Telescopes, including the First G-APD Cherenkov Telescope (FACT), use multiple mirror reflectors. These reflectors offer a great performance for very little resources. However one challange of multiple mirror reflectors is the alignment of the single mirrors to gain a good image. To align the FACT reflector a method developed by the VERITAS group was adopted and enhanced. Using a 1/10th scale model of FACT, the alignment system was developed off site in the lab which results in a highly telescope independent procedure. Finally FACT's reflector was aligned using all new Bokeh alignment and fine adjusted using enhanced SCCAN in May 2014. The basic alignment system and the alignment procedure on the telescope are presented. Alignment results are presented by comparison of star images using visible light and actual muon detection rates to compare the overall telescope performance before and after the reflector alignment.
