  • Svbony MK90 90mm Maksutov-Cassegrain Telescope

    The Svbony MK90 puts a 90mm Maksutov-Cassegrain optical system into a highly portable package for detailed lunar, planetary, and terrestrial viewing. It connects to standard astronomical mounts using the included 70mm Vixen-style dovetail plate and is compatible with all 1.25-inch eyepieces and accessories.

    The 90mm Maksutov-Cassegrain Optical System

    The MK90's two-element Maksutov-Cassegrain optics deliver the sharp, high-contrast images this design is known for. The 90mm aperture gathers enough light for definitive views of the Moon's craters, Jupiter's cloud belts, and the rings of Saturn. This long focal length design excels at high magnification, making it an ideal instrument for planetary observers who need crisp detail.

    While perfect for celestial targets, the Maksutov design also produces a correctly oriented image (with an optional diagonal), making the MK90 a powerful spotting scope for daytime bird watching and nature observation. The trade-off for its high-power planetary resolution is a narrower field of view compared to a short-tube refractor, making it less suited for sweeping across the widest sections of the Milky Way.

    Advanced Internal Baffling for High-Contrast Views

    Svbony has engineered the MK90 with a tapered internal baffle tube specifically designed to intercept and absorb stray light. This feature is critical for maintaining image contrast, especially when observing bright objects like the Moon or planets against the blackness of space. By preventing off-axis light from reaching the focal plane, the background sky remains darker and subtle surface details are more easily visible.

    A Versatile 70mm Vixen Dovetail & Tripod Mount

    The MK90 optical tube is built for versatility in the field. It includes a 70mm Vixen-style dovetail plate, the de-facto standard for most modern astronomical alt-azimuth and equatorial mounts. For more casual or terrestrial use, the mounting base also includes a standard UNC ¼-20 threaded hole, allowing you to attach the telescope directly to a sturdy photographic tripod without any additional hardware.

  • What kind of mount do I need for the Svbony MK90 telescope?

    The Svbony MK90 is very flexible. It comes with a 70mm Vixen-style dovetail plate that fits most modern astronomical mounts, like the Celestron AVX or Sky-Watcher EQ6-R. It also has a standard ¼-20 threaded hole, so you can mount it directly onto a heavy-duty photo or video tripod for daytime use or quick astronomical viewing sessions.

    Is the Svbony MK90 good for bird watching?

    Yes, it's an excellent choice for terrestrial viewing like bird watching. The Maksutov-Cassegrain design provides high magnification and sharp images. When used with a 1.25-inch correct-image prism diagonal (sold separately), the view will be upright and correctly oriented left-to-right, making it easy to track moving subjects.

    How does the internal baffle in the Svbony MK90 improve views?

    The internal baffle is a tube inside the telescope that blocks stray light from bouncing around and washing out the image. This results in a darker sky background and higher contrast, which is especially important for seeing faint details on planets or separating the subtle shades in lunar craters.

    Can I see the rings of Saturn with the Svbony MK90?

    Absolutely. The 90mm aperture and long focal length of the Svbony MK90 are ideal for Saturn. On a night with steady air, you will be able to clearly resolve the rings as distinct from the planet itself and may even glimpse the Cassini Division, the largest gap in the rings.

    How will the Svbony MK90 perform for observing the Moon from a light-polluted city?

    The Moon is bright enough to be unaffected by light pollution, and the Svbony MK90 is an excellent instrument for lunar observation from any location. Its high-resolution optics will allow you to explore mountain ranges, craters, and rilles in sharp detail, even from a city balcony.

    What eyepieces should I start with for the Svbony MK90?

    A good starting set for the Svbony MK90 would include two 1.25-inch Plössl eyepieces:

    • A low-power eyepiece (around 25mm-32mm) for finding objects and wide views.
    • A high-power eyepiece (around 9mm-12mm) for detailed views of the Moon and planets.
  • Optical Design Maksutov-Cassegrain
