 ===== Photography with a DSRL =====
-We have a Canon EOS 700D, which is a digital (single) reflex camera (DSLR). This camera allows for very short exposure times (until 1/4000s), while our CCDs only allow for a minimal exposure time of 0.09s. Accordingly, this camera is useful for objects that require short exposure times. Please note that those objects need to be bright enough for such short exposure times. The field of view of the DSLR is larger compared to the other cameras (see [[en::ost:ccds:grunddaten|here]]).

+**Our new camera, the QHY600M, is a CMOS camera and therefore also allows much shorter exposure times than the old CCD cameras and on the other hand does not have the disadvantages of a DSLR camera, such as a high dark current. More about this when we have more experience... :-).**
