About Explore Scientific FirstLight 203mm f/6

What sets the FirstLight 203mm f/6 N1218mm Dobsonian Telescope apart is its revolutionary design that has transformed amateur astronomy. The Dobsonian telescope, pioneered by John Dobson, democratized stargazing by combining large aperture optics with a simple, yet stable mount, making celestial wonders like the polar caps of Mars and the rings of Saturn accessible to all. Explore Scientific elevates this tradition with a versatile universal design that allows the Dobsonian to be converted into a Newtonian telescope, perfect for those looking to delve into astrophotography.

This model features a robust 2.5" HEX focuser, providing unparalleled rigidity and smooth focusing, accommodating both 1.25" and 2" eyepieces. This inclusion is a significant advancement for telescopes in this price range, ensuring sharp, clear images. The telescope comes with a Red Dot viewfinder and a 25mm SPL eyepiece, enhancing your celestial viewing experience right out of the box.

Transportation and storage are made effortless with the FirstLight Dobsonian's innovative design. The Rockerbox mount can be quickly disassembled using metal quick connectors, transforming the telescope into a conveniently compact package. This feature makes it an ideal choice for astronomers who value both performance and portability.

The FirstLight 203mm Dobsonian is not only a gateway to observing deep sky wonders but also a tool that brings out intricate details on planetary surfaces. Even novice observers can enjoy crisp views of star clusters and the mesmerizing terminator line on the moon. For those seeking to optimize their viewing experience, the telescope is ready to be enhanced with our optional coma corrector.

In summary, the FirstLight 203mm f/6 N1218mm Dobsonian Telescope with Manual Alt-Azimuth Mount is a testament to Explore Scientific's commitment to quality and innovation.
