Launch Visual AssistantThe Sidara Plus 150 packages a 150mm Newtonian reflector with a 750mm focal length to create a dedicated deep sky observing instrument that remains highly portable. Its fast f/5 focal ratio produces a bright, wide field of view, critical for framing large star clusters and faint nebulae that longer focal length systems struggle to contain in a single view.
The core of the Sidara Plus 150 is its 150mm primary mirror. This aperture gathers a significant amount of light, resolving dust lanes in the Andromeda Galaxy (M31) and individual stars in globular clusters like the Hercules Cluster (M13). The 750mm focal length results in an f/5 optical system, which provides brighter images at any given magnification compared to an f/10 system, making faint objects stand out more readily against the background sky.
This system includes the Sidara Plus alt-azimuth mount, a medium-duty mount sized to handle the load of the 150mm Newtonian reflector. Integrated slow-motion control knobs allow for fine, smooth adjustments on both axes, letting you track objects seamlessly as they drift across the sky. This precision tracking keeps your target centered, avoiding the frustration of constantly re-aiming the telescope.
The Sidara Plus 150 features SkyAssist integration to help you locate celestial objects quickly and efficiently. This system simplifies navigating the night sky, acting as a guide to help you point the telescope at your desired target. Instead of spending valuable time hunting for faint objects, SkyAssist allows you to spend more time observing them, making it an ideal tool for users looking to deepen their exploration of the cosmos.
The Sidara Plus 150 excels at observing large, faint deep sky objects thanks to its 150mm aperture and fast f/5 focal ratio. It is ideal for sweeping the Milky Way for open star clusters, viewing large emission nebulae like the Orion Nebula (M42), and framing galaxies like Andromeda (M31) and Triangulum (M33).
No, the Sidara Plus 150 is designed for ease of use. The Sidara Plus mount is a simple alt-azimuth design that is intuitive to point and move. With the addition of SkyAssist, finding objects is much simpler than with a traditional star chart, making it accessible for observers of all levels.
SkyAssist is a navigation aid that works with the mount to help you locate celestial objects. It simplifies the process of "star hopping" or manually finding targets by providing guidance, allowing you to quickly slew the telescope to the correct area of the sky to begin observing.
Yes. While the telescope's wide field is optimized for deep sky objects, it is also perfectly capable of observing planets. The Sidara Plus mount's smooth slow-motion controls allow you to easily track Jupiter and its moons, or the rings of Saturn, as they move across the sky.
The Sidara Plus 150's combination of a 150mm aperture and a wide field of view is excellent for M31. From a dark sky site, you will be able to see the bright galactic core, the extended glow of the spiral arms, and potentially hints of its dark dust lanes. Its two companion galaxies, M32 and M110, will also be visible in the same field of view.
Portability comes mainly from the relatively short optical tube. The medium-duty Sidara Plus mount and tripod weigh 16.7 lb (7.6 kg), so the system is portable rather than ultralight and can still be taken to dark sky locations away from city lights for the best possible views.
