Abstract

Embodiments of the present disclosure include user-directed automated telescope alignment systems and methods. In various embodiments, the automated alignment procedure provides for user-direction in selecting astronomical alignment objects. For example, in an embodiment, after the telescope is aligned according to a first approximation alignment, the user may direct the field of view of the telescope system to a viewable, sufficiently bright astronomical object. Upon bringing the object into the field of view, the alignment procedure advantageously identifies the likely astronomical object based on the first approximation alignment. The procedure also updates the first approximation alignment based on known information about the identified object. The process of user-direction to additional viewable bright astronomical objects provides for more precise and accurate mappings of telescope movements to celestial field of view.

Claims

1. A method of improving an alignment of a field of view of a telescope, the method comprising:

establishing a first approximation alignment of a field of view of a telescope system;

receiving an indication that a user has directed the field of view to an astronomical alignment object selected by the user from astronomical objects presently accessible;

electronically identifying celestial coordinates for the astronomical alignment object based on the first approximation alignment; and

electronically updating the first approximation alignment of the field of view based on the identified celestial coordinates.

2. The method of claim 1, wherein said user direction is performed manually by the user.

3. The method of claim 1, wherein said user direction is performed by a positioning system under the control of the user.

4. The method of claim 1, wherein said astronomical alignment object is bright.

5. The method of claim 1, wherein said electronically identifying celestial coordinates for the astronomical alignment object comprises:

electronically determining estimated celestial coordinates for the object based on the first approximation alignment;

electronically determining one or more candidate objects based on the estimated celestial coordinates;

electronically identifying one of the candidate objects as corresponding to the astronomical alignment object; and

electronically determining the celestial coordinates for the identified candidate.

6. The method of claim 5, wherein said electronically identifying one of the candidate objects comprises selecting the candidate object with celestial coordinates having the smallest angular distance from the estimated celestial coordinates.

7. The method of claim 5, wherein said electronically identifying one of the candidate objects comprises selecting the candidate object with the greatest apparent brightness within a predetermined distance from the estimated celestial coordinates.

an optical system including a field of view;

a positioning system adapted to precisely position the filed of view of the optical system; and

a processor configured to determine a first approximation alignment of the field of view, to receive an indication that a user has manipulated the positioning system to cause the field of view to be directed toward an astronomical alignment object selected by the user from astronomical objects presently accessible, to electronically identify celestial coordinates for the astronomical alignment object based on the first approximation alignment, and to electronically update the first approximation alignment of the field of view based on the identified celestial coordinates.
