R A and declination Dec slow motion control knobs allow fine adjustment of the telescope s position to center objects within the field of view Before you can use the knobs you must manually slew the mount to point the telescope in the vicinity of the desired target Do this by loos ening the R A and Dec lock levers and moving the telescope about the mount s right ascension and declination axes Onc...
