Definitions

  • the present invention relates to astronomical telescope mountings and, more particularly, to user interfaces for such mountings.
  • Telescopes for observing and/or photographing celestial objects are well known.
  • Common types of astronomical telescopes include refractor telescopes, reflector telescopes and catadioptic (compound) types.
  • Astronomical telescopes are normally mounted upon mountings typically having two orthogonal axes of rotation. Rotation around these axes allows the telescope to be pointed in any arbitrary direction.
  • the rotation around each axis is typically driven by a kind of drive unit. These drive units can be manually or electrical driven via a handle or a motor (see US 4,709,178).
  • the wish to have a motorized telescope mounting originate from the need to be able to compensate for the earth rotation by turning the telescope very slowly keeping a celestial object centered in the telescopes field of view over extended periods of time. All kinds of photographic observations need the telescope to precisely track the object as it moves across the sky.
  • the earliest telescope mountings had mechanical clocks as the drive units. Later, different kinds of electrical motor driven units have been used. Introduction of modern types of motors e.g. step motors or servo motors made it possible to slew the telescope between different objects using the drive units on the mounting axes. This caused the need for a user interface to enable the observer to control the motors of the mounting and point the telescope towards selected objects.
  • microprocessor controlled telescope mountings have brought a number of new possibilities such as, automatic pointing to selected objects, tracking fast moving objects e.g. satellites, movement in spherical coordinate systems with axes not coincident with the mountings movement axes etc.
  • User interfaces used to control these microprocessor controlled telescope mountings are all based on pushbuttons alone.
  • the typical user interface contains 4 main pushbuttons to activate the movement of the mounting in the four possible directions and moreover a number of pushbuttons to receive other inputs to the microprocessor.
  • a kind of keyboard is used for the input of data and in other cases a limited number of pushbuttons are used to select between different commands presented to the user on a display (see US 6,392,799 fig- 5a, fig. 6a).
  • the objective of the present invention is to create a user interface that is easier to use in darkness and when wearing gloves.
  • the use of, one or more rotational encoders for sensing user inputs gives the possibl ⁇ ty to construct a user interface based on a few large rotational knobs for handling all user inputs. These knobs are very easy to identify and operate in complete darkness and wearing gloves. Additionally it gives the user new improved possibilities for adjusting the movements and position of the telescope.
  • the invention consists of a control unit that uses two rotational knobs with encoders, to control the movement of the telescope mounting around two axes in a spherical coordinate system.
  • the connected encoder When a user turns one of the knobs, the connected encoder sends signals to a data processing unit The data processing unit processes these signals and commands the motors to perform a certain motion around the relevant axis.
  • the relationship between the turning of the knobs and the movements of the mounting can, by the user, be selected to follow different rules.
  • One possibility is to have a certain angular movement of a knob resulting in a certain angular movement of the telescope mounting around one axis, in one spherical coordinate system.
  • Another possibility is to have a certain angular movement of a knob resulting in the telescope mounting rotating at a certain speed around one axis, in one spherical coordinate system, until another control signal is given.
  • the speed at which a knob is rotated can also be used to control the movements of the mounting. Besides the above described relations between the movements of the knobs and the resulting movements of the mounting several other relations are possible.
  • the rotational knobs are also used for inputting data to the software applications used for controlling the telescope mounting. They are among others things used for scrolling in menu's, scrolling in lists and scrolling in alphanumerical sets of characters.
  • Fig.l shows one possible embodiment of a telescope user interface in accordance with the present invention.
  • the altitude rotational knob (1) is connected to an encoder that gives signals to a microprocessor. Based on these signals the microprocessor calculates control signals for the two motors in the telescope mounting . Often, but not always, the altitude rotational knob is used for controling the motor that operates the altitude or the declination axis.
  • the azimuth rotational knob (2) is connected in the same way as the altitude rotational knob. Often, but not always, the azimuth rotational knob is used for controlling the motor that operates the azimuth or the right ascension axis. Both rotational knobs are used for scrolling and selecting in software menues showed on the display (3) and for inputting data necessary for the use of the telescope mounting.

Abstract

L’invention concerne des interfaces utilisateurs pour des montages de télescopes astronomiques qui sont normalement basées sur des boutons poussoirs. L’interface utilisateur selon l’invention utilise des codeurs rotatifs en tant que dispositif d’entrée des utilisateurs. Les signaux provenant des codeurs rotatifs sont transformés par l’intermédiaire d’une unité de traitement de données en des signaux de commande pour un ou plusieurs moteurs pilotant le mouvement du montage de télescope. La transformation des signaux provenant des codeurs rotatifs en des signaux de commande de moteur peut être faite sur la base de différents principes donnant à l’utilisateur la possibilité de réaliser des tâches de commande avancées grâce à une interface très simple.
