The telescope had initial challenges with regard to image quality (IQ). The efficiency of the spectrograph was greatly reduced compared to what had been expected. A lengthy repair process followed, involving the dismantling and testing of all optical components verifying their optical condition and cleaning them where necessary. The mirrors were all realigned and tested with a computer generated hologram. It was later reported that the viewing which took place that night, had been very successful and very good astronomical images had been obtained.
