| 15 | 15 | You may also use the science CCD. It has a field of view of 15' times 15', which corresponds to 1024 times 1024 Pixels with a pixel scale of 0.9". The CCD is cooled to -120 degree Celsius by means of liquid Nitrogen. Parts of the electronic are similar to the one used on Calar Alto, as mentioned above. With just a few minutes exposure the camera reaches objects of 17th magnitude. Thanks to a newly improved tracking it is indeed now possible to integrate for ten minutes or even longer. With this camera students have the opportunity to learn vital observational techniques: how to stear a telescope or a camera, how to plan an observing run, how to monitor the data you get while you get it ... This all makes up a very good preparation for observations with bigger telescopes. And, naturally, we also take some beautiful pictures of known and not so known objects. |
