Explore Scientific FirstLight overview

  • 1Description

The Explore Scientific FirstLight 152mm f/12.5 GoTo Maksutov-Cassegrain Telescope is ideal for users who want a portable yet powerful observation platform that is able to achieve high magnifications and has the ability to make detailed observations of both near- and deep-sky subjects. The Maksutov-Cassegrain optical configuration is engineered with a convex meniscus lens that not only eliminates the need for periodic collimation, but by the nature of the lens requires a smaller secondary mirror that limits obstruction and increases contrast. The Maksutov optical path results in a slower focal ratio and narrower field of view versus a similar-sized Schmidt design, but the optical benefits make this a useful scope for planetary and double-star observation.

The SkyTracker kit includes the hand controller unit and right ascension and declination motors. Its hand controller has a database of more than 272,000 objects with the ability for users to input custom coordinates and favorites. With a slew speed of 2° per second and nine tracking speeds, the SkyTracker can accurately keep near- and deep-sky objects such as the Moon, planets, galaxies, and nebulae centered in your eyepiece for long-exposure imaging and astrophotography or prolonged observation sessions.

The tripod is built with large 2"-diameter stainless steel legs and tight tolerances to reduce vibrations, for clearer viewing. A center stabilizer bar pulls the accessory tray up to lock the legs in place, adding further rigidity and vibration reduction. It is adjustable from 29 to 43" to accommodate a wide range of users and features large thumbscrews for tool-free adjustment in the field. An adjustable tray is also included with the tripod to keep eyepieces, flashlights, and other accessories safe and at the ready. Rounding out the included accessories is a 25mm eyepiece, a 90° star diagonal for comfortable viewing, a universal smartphone holder for capturing images through the eyepiece, and an unmagnified red-dot finder.
