Explore Scientific FirstLight 100mm Mak-Cassegrain with EQ3 Mount - Discontinued

The FirstLight 100mm Mak-Cassegrain excels at high-magnification viewing of bright solar system objects. Its long focal length is ideal for observing fine details like the craters and mountains on the Moon, the cloud bands and Great Red Spot on Jupiter, the rings of Saturn, and the phases of Venus.

The EQ3 is a German equatorial mount that, when aligned with Polaris (the North Star), tracks celestial objects with the turn of a single knob. This counteracts the Earth's rotation, keeping your target centered in the eyepiece. This is crucial for high-power planetary viewing, where objects would otherwise drift out of view very quickly.

Yes. One of the key benefits of the Maksutov-Cassegrain design is its compact and lightweight optical tube. This, combined with the manageable size of the EQ3 mount, makes the entire system easy to transport for trips to dark-sky locations or for setting up quickly in your backyard.

Under steady atmospheric conditions, the FirstLight 100mm Mak-Cassegrain can reveal significant detail on Jupiter. You can expect to clearly see its two main equatorial belts, subtler cloud bands, and the four Galilean moons (Io, Europa, Ganymede, and Callisto). On nights of good seeing, you may also be able to glimpse the Great Red Spot.

While this telescope is optimized for planets, it is still capable of viewing brighter deep-sky objects like the Orion Nebula (M42). You will be able to see the core region and the Trapezium star cluster within it. However, its narrow field of view means you won't see the full expanse of larger nebulae or star clusters in a single view.

Yes, the package is designed for beginners and includes all the core components. It comes with the telescope tube, the EQ3 mount and tripod, a Plössl eyepiece, a star diagonal, a red-dot finder for aiming the scope, and a smartphone adapter for taking pictures of the Moon and bright planets.
