Parabolic main mirror
The main mirror has a parabolic shape to minimize optical distortion when observing at high magnifications. Its surface is coated with an aluminium coating with a reflectivity index of 92-96%. This has a positive effect on the contrast and brightness of the transmitted image. You can adjust the focus using the Crayford two-speed achromatic eyepiece lift. It has no recoil and holds even heavy optical accessories securely in place for fast and accurate focusing.
Dobson type mounting with improved bearing on the brake system side
The telescope includes a classic Dobsonian mount. It has a conventional design and all the advantages of this type of mounting, but at the same time its mechanics have been significantly improved. Special bearing on the side of the braking system for smooth tube movement allows the optical tube to be moved up or down a few centimetres. When using additional attachments, this system quickly balances the telescope and maximizes stability. Scales are located on the sides of the assembly for convenient balancing. The bearings are also durable and provide smoother movement, which is important when using binoculars with high magnifications.
Active optics cooling
The rear cover of the telescope tube contains the cooling fan. It provides thermal stabilization of the optics almost twice as fast, so you can start observing much faster. The fan is battery operated (purchased separately).
