BOOTES-1B is a 30 cm Meade Schmidt-Cassegrain telescope on a fast slewing Paramount-ME mount, equipped with an Andor iXon 889 512x512 pixel EMCCD camera. It's primary objective is follow-up of satellite GRB alerts. It can interrupt the ongoing observation, slew and start acquiring images of the proposed GRB location with a typical delay of 30s after the alert reception. Typical limiting magnitude of the earliest 2-second unfiltered exposures is 15. Later, with 60s exposures, a limiting magnitude of about 18 can be achieved. | BOOTES-1B is a 30 cm Meade Schmidt-Cassegrain telescope on a fast slewing Paramount-ME mount, equipped with a FLI CM-8 1536x1024 pixel (Kodak KAF1602) CCD camera. It's primary objective is follow-up of satellite GRB alerts. It can interrupt the ongoing observation, slew and start acquiring images of the proposed GRB location with a typical delay of 30s after the alert reception. Typical limiting magnitude of the earliest 10-second unfiltered exposures is 15. Later, with longer exposures, a limiting magnitude of about 18 can be achieved. |

The telescope observes without filters to maximize throughput. Its current configuration with the Meade 1:6.3 focal reducer and the CCD provides an image scale of 1.96”/pixel and a field of view of 16.7'x16.7' (F=1684mm, or f/5.5). | The telescope observes without filters to maximize throughput.

Since its installation the telescope has followed 5 GRBs with positive detections. These are GRB 080330, GRB 080413A, GRB 080430, GRB 080603B and GRB 080605. | Since its installation the telescope has followed 5 GRBs with positive detections.

As an independent robotic observatory, BOOTES has various devices to sense the weather. Currently, a multi level decision model in order to decide whether to observe or not. The following detectors are used during the decision whether the observation is possible or not. | As an independent robotic observatory, BOOTES has various devices to sense the weather.
