20cm short minimum focus
The AT-B Series can focus on objects 20cm in front of the telescope. This feature dramatically facilitates working in confined spaces.
 
All-weather dependability
With the IPX6 rating, the instrument is protected against powerful water jets from all directions, meaning the AT-B Series withstands a sudden shower of torrential rainfall. The advanced protection design also deters clouding or condensation inside the telescope.
