Description

  The present invention relates to a telescope and a tripod connecting member.

  For example, wild birds may be observed and photographed with a terrestrial telescope (hereinafter referred to as a telescope) attached to a tripod. At this time, different eyepieces with different weights are used for the telescope body depending on the magnification, field of view, etc., or a camera is attached to the rear of the telescope body or eyepiece.

  If the tripod is not attached to the appropriate center of gravity of the telescope during observation and photographing, the telescope is not stable and the telescope is likely to shake or fall over.

In order to prevent this, a tripod that has improved the stability of the telescope using a tripod head that can move the tripod screw in the front-rear direction (the telescope optical axis direction) is known (Gakken, “Photos of the Four Seasons” 2003) (See the December / January issue). According to this tripod, it is possible to prevent the telescope from shaking or falling.

  However, since the above tripod is configured to be compatible with many commercially available telescopes, the structure of the pan head is complicated, and the pan head is large and heavy. Therefore, the tripod is large and expensive.

  The present invention has been made in view of such circumstances, and a problem thereof is to prevent the telescope from being shaken or toppled at a low cost.

  In order to solve the above-mentioned problems, the invention according to claim 1 is a telescope main body, a tripod connecting member mounting portion provided on a tripod mounting side of the telescope main body, and a tripod connecting member mounting portion. And a tripod connecting member having a position changing member for changing a relative position of the tripod connecting member mounting portion with respect to the base in the telescope optical axis direction.

  According to a second aspect of the present invention, in the telescope according to the first aspect, the position changing member is a female screw, the mounting direction of the tripod connecting member with respect to the tripod connecting member mounting portion can be reversed, and the position changing member The position in the optical axis direction can be changed.

  According to a third aspect of the present invention, in the telescope according to the first aspect, the position changing member is a female screw, and the tripod connecting member is mounted on a guide portion of the tripod connecting member mounting portion so as to be movable in the telescope optical axis direction. It is characterized by.

  The invention according to claim 4 is a position that is mounted on a tripod connecting member mounting portion provided on a tripod mounting side of the telescope body, and changes a relative position of the tripod connecting member mounting portion with respect to the tripod head in the telescope optical axis direction. A changing member is provided.

  According to a fifth aspect of the present invention, in the tripod connecting member according to the fourth aspect of the present invention, the tripod connecting member mounting portion is detachable.
