Description
Technical field
The utility model relates to a kind of astronomical telescope.
Background technology
Traditional astronomical telescope all is equipped with a finder, but this finder is the outer body tube outside that is connected on, and needs to do correction before use, could normally use.The structure of existing body tube as shown in Figure 1.Because existing this finder system because finder and body tube not on coaxial, in any case proofread and correct, always have an angle between finder and the body tube, so in use to target and the in-plant target of infinite distance, finder has certain deviation, finder in the process of adjusting because with the body tube multiplying power differ be difficult to more greatly to adjust to real concentric.
The utility model content
The built-in coaxial star astronomical telescope of seeking that provides a kind of finder and telescope coaxial is provided the purpose of this utility model.
The technical solution of the utility model is as follows: it comprises body tube principal goods mirror, the secondary catoptron of principal goods mirror, and it is characterized in that: it also comprises finder principal goods mirror, described finder principal goods mirror and the coaxial setting of body tube principal goods mirror.
Body tube principal goods mirror in telescopical first (group) is coaxially installed with finder principal goods mirror.
Advantage of the present utility model is: do not need finder is carried out extra assembling and debugging, directly reach the coaxial star purpose of seeking, being different from traditional finder can place finder in the optimum position of primary mirror barrel, and the position of hommization is beneficial to observation more.

Embodiment:
Shown in Fig. 2-5, technological core of the present utility model is on the basis of existing Cassegrain's optical system or Maksutov's optical system telescope (as shown in Figure 1), with body tube principal goods mirror a and the coaxial setting of finder principal goods mirror b.The concrete structure of its coaxial setting can have multiple.
The utility model also comprises the oblique mirror of finder or prism e and finder eyepiece group; Be linked in sequence by finder principal goods mirror b, the oblique mirror of finder or prism e, according to light path and form finder master objective lens; Primary mirror barrel in the oblique mirror of finder or prism e light path reflecting surface correspondence offers finder eyepiece mounting hole m, and a whole set of finder eyepiece group is installed on the finder eyepiece mounting hole m, and the secondary catoptron g of principal goods mirror also is housed in the fixed mount.
The utility model also comprises fixed mount; Described fixed mount is the penetrating cylindrical shapes in two ends, offers reflective through hole l at the wall of fixed mount, and the reflected light of the oblique mirror of finder or prism e reflexes to finder eyepiece group from reflective through hole (l).
Embodiment 1:
As shown in Figure 2, (be central authorities' punching a) of body tube principal goods mirror, at this hole installation finder principal goods mirror b, make finder principal goods mirror b and body tube principal goods mirror a on coaxial at existing telescopical first (group) glass.Described finder master objective lens is fixed in the fixed mount k; The fixed mount that finder master objective lens is installed is sleeved on this hole, and described fixed mount adopts lighttight material to make, and it can play the interception on light hurdle; Play the effect of finder lens barrel simultaneously, also be arranged with light hurdle j on the fixed mount outside the secondary catoptron g of principal goods mirror.Between body tube principal goods mirror (a) and finder principal goods mirror (b), be provided with the light hurdle that plays the effect of cutting apart the different light paths zone.
Between body tube principal goods mirror a and finder principal goods mirror b, be provided with fixed mount k.A whole set of star searching system is installed for convenience, earlier finder principal goods mirror, the oblique mirror of finder or prism e, the secondary catoptron g of principal goods mirror and light hurdle j is arranged on the fixed mount k; Described fixed mount k is cylindrical shape.
Embodiment 2:
As shown in Figure 3, (central authorities that are body tube principal goods mirror front and back a) arrange (pasting or one-body molded or other combination) finder principal goods mirror b1, b2 respectively, are sequentially provided with finder principal goods mirror b2, the oblique mirror of finder or prism e, the secondary catoptron g of principal goods mirror in body tube principal goods mirror a and fixed mount at telescopical first (group) glass; Also be arranged with light hurdle j on the fixed mount outside the secondary catoptron g of principal goods mirror.
Embodiment 3:
As shown in Figure 4, (central authorities that are body tube principal goods mirror front a) arrange a finder principal goods mirror b, are provided with the secondary catoptron g of the oblique mirror of finder or prism e and principal goods mirror in fixed mount at telescopical first (group) glass; In the zone of the central authorities at the back side of body tube principal goods mirror a, corresponding finder principal goods mirror b is fixedly connected with, be provided with the fixed mount of the secondary catoptron g of the oblique mirror of finder or prism e and principal goods mirror, also be arranged with light hurdle j on the fixed mount outside the secondary catoptron g of principal goods mirror.
Embodiment 4:
