The very small area of sky observable with the existing CCD, is a problem when larger fields need to be observed. A focal reducer was installed on the telescope thus increasing the observed area by a factor of about 4. The advantage is faster photometry and detection of very faint stars (&gt;20 mag). A permanent focal reducer should be mounted on the telescope for the benefit of all observers.</style></abstract></record></records></xml>
