Sky-Watcher 254/1200 DOB 10" Pyrex telescope (aka Dob 10" Classic 250P)

This telescope is particularly well-suited for observing nebulae, open spherical clusters, and a wide variety of captivating galaxies. It's important to note that the telescope's range also encompasses all the planets in our solar system, along with many of their moons.

When it comes to observing our natural satellite, the telescope delivers impressive results. However, due to the abundance of light during a nearly full moon, it is advisable to use a filter, preferably a neutral gray (neutral density) filter. With a large mirror slightly over 25 centimeters in size, this telescope collects over 1300 times more light than the human eye. In comparison to the popular Synta 8" (203 mm) telescope, the Sky-Watcher Dobson 10" provides a 56% increase in light-gathering ability.

The mirror is crafted from Pyrex glass, which is a boron-silicon glass consisting of 8% boron oxide and 85% silicon oxide. The inclusion of boron oxide makes the mirror lighter and, more importantly, results in a lower coefficient of thermal expansion. This positively impacts the quality of the obtained images.

Beyond the mirror's significance, the telescope is also well-designed and equipped with premium features. It boasts a focal length of 1200 mm, offering a large aperture of f/4.7. The telescope is equipped with a top-notch 2-inch Crayford focuser that includes a reduction to 1.25", a large 9x50 finder, and two Ploessl eyepieces (25 mm and 10 mm). Additionally, the telescope features an intuitively simple Dobsonian azimuthal mount. The focuser even has a T-2 thread, allowing users to attach a reflex camera and capture stunning images of bright objects. However, it is essential to ensure proper reduction for your specific camera brand, such as Canon, Nikon, Sony Alpha, Pentax, or Olympus.

The Dobsonian mount is renowned for being the simplest and most affordable type of telescope assembly, making it highly suitable for visual observations. The mount's control involves manual adjustments in the azimuthal (horizontal) and vertical (height) axes.

In terms of physical dimensions, the telescope consists of an optical tube measuring 113x28 cm and weighing 12.5 kg. The accompanying azimuthal mount weighs an additional 12.5 kg. The telescope is originally packaged in two sturdy cardboard boxes and is ready for observation once the assembly is completed and properly collimated.

The Sky-Watcher Dobson 10" telescope is manufactured by the reputable Synta factory, known for producing high-quality telescopes under various brand names such as Celestron, SkyWatcher, Omegon, Orion, Spinor Optics, Pentaflex, and others.
