We dispose of this equipment:

* THE   TELESCOPE: We dispose of a 10” (253 mm) opening and 2500 mm focal distance Schmidt-Cassegrain-type telescope; it is mounted on a fork assembly and full automatic. It is the LX200 GPS model of MEADE manufactor.

For comparison: When disposing of a conventional, classic optical construction schedule, the entire system would have to be mounted on a 2.5 m tube. (The actual length of our telescope’s tube is considerably shorter due to its highly developed optical system).

 

 

The following figure shows the optical schedule of the Schmidt-Cassegrain-type:

Its operating mode is as follows: The incident light at first crosses the Schmidt correction sheet whose task consists in correcting the spherical aberration of the mirrors. Thus we achieve that the couple of spherical-non-spherical mirrors is equivalent to a couple of concave-convex mirrors.

Following, the light reaches the primary mirror which is a spherical mirror concentrating the light onto the secondary mirror, this way creating a first amplification. On its centre there is a “Cassegrain” called hole which the light directed to the ocular passes through.

Finally the light is being reflected on the secondary mirror which is a non-spherical mirror that concentrates the light on the focal plane, right where the ocular had been installed. Thus, this mirror causes a second amplification.

This optical Schedule is similar to those of the large telescopes being used at astronomic observatories, and allows achieving superior performances using a relatively compact structure.

 

*The telescope’s performances: Among the elements (ocular and other accessories) we dispose of, there are particularly a diagonal 2" prism which corrects the image’s resolution, as well as a 2" wide-area ocular. Concretely it is about the LV 50 model of VIXEN manufactor. This ocular, with its 50 mm focus, allows us observing large objects at an enormous quality.

*The computer: As well we dispose of a portable computer (lap top). With the help of this device we can illustrate all the explanations being made during the observing session. On the display we can view relevant pictures and data of each object being observed on the telescope.

 Likewise, we dispose of very interesting programmes as for example a starmap for showing details of the ceiling’s configuration, and also positioning-simulators of Jupiter’s and Saturn’s satellites; which is very useful while obseving these planets.

The laptop’s possibilities go farer, there are more features being tested.
