The eyepiece turret is a device that can be installed with multiple eyepieces, and the magnification can be changed only by rotating without changing the eyepiece during observation. Turret is widely used abroad, but there are few domestic products, and there are no high-end products. This product can be said to fill the domestic gap!
The turret is designed with a 2-inch 4-interface design. It can be compatible with 1.25 inch eyepiece downward through the adapter ring. The number of 4 2-inch interfaces is just right. If 5-6 interfaces are added, the volume and weight will increase a lot. If the 1.25 inch interfaces are expanded to 6, there will be light leakage interference between each other. Therefore, the 4-interface scheme is finally selected.
The reflector adopts customized medium high reflective film lens, and the PV after coating is higher than 1/8 (higher before coating).
For the body, the aluminum alloy machining center is used for overall milling to ensure stability and accuracy; Bearing non friction rotation is adopted for rotation, and special positioning device (not simple glass bead positioning) ensures stability and durability; Screw lock is adopted for the lock, and the non ordinary copper plate lock ensures the concentricity and locking force of the lock; The shell is anodized and will not fade after long-term use.
The objective lens end interface can be equipped with a 2-inch socket, SCT, M63 * 1 and other special interfaces (the price is calculated separately) to adapt to the refractor, schka, etc. It is connected to the turret body through the V port and the jackscrew to facilitate the alignment and positioning during installation! As the 2-inch eyepiece is heavy, it is generally recommended to directly screw it to the focusing seat to avoid loss due to slipping!
In terms of optical path, the body occupies 122mm optical path, which is only 20mm more than the ordinary 2-inch zenith mirror. Most mirrors can be directly focused. Weight 1.2KG, much lighter than foreign products!
