-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.

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).

 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.
