Comparison Review: Sky-Watcher Virtuoso GTi 130P and GTi 150P Astronomical Telescopes
The Sky-Watcher Virtuoso GTi 130P and GTi 150P telescopes stand out in the realm of amateur astronomy, combining the renowned design of the Heritage 130P and 150P tabletop Dobsonians with cutting-edge technology. These bad boys provide a perfect balance between simplicity and sophistication.
The heart of the Virtuoso GTi series lies in their 130mm and 150mm optical tubes, which deliver impressive wide-field views of star clusters and nebulae, all while offering enough light-gathering power to glimpse smaller deep-sky objects like planetary nebulae, globular star clusters, and even galaxies under a dark sky. Their optics shine bright on Solar System objects too, delivering razor-sharp views of the Moon, planets, and double stars. Bonus points for their collapsible tubes and tabletop mounts, making them not only portable but also airline-friendly when disassembled.
The main enhancement of the Virtuoso GTi series is the addition of GoTo technology, a system that automatically locates and tracks celestial objects, making them a lifesaver for beginners or those pressed for time. The app-controlled Virtuoso GTi runs on quiet, high-quality motors, consuming minimal power and offering precise tracking for hours on end. Another critical feature is the FreedomFind dual encoders, allowing manual adjustments without interfering with the telescope's GoTo functionality.
The Virtuoso GTi can also be mounted on a tripod, giving it added portability. In terms of cost-effectiveness, the Virtuoso GTi offers exceptional value, blending affordability, advanced features, and top-notch optics.For those looking to explore the cosmos, the Sky-Watcher Virtuoso GTi 130P and 150P are the way to go.
The Great Debate: Virtuoso GTi 130P vs 150P
The primary difference between the two lies in their aperture sizes, with the 150P boasting an impressive 150mm (6 inches), about 33% more than the 130P's 130mm (5.1 inches). This extra inch makes the 150P a stellar performer when it comes to deep-sky observation, delivering brighter and more detailed images of faint deep-sky objects. With greater light-gathering power, you can spot subtle features like Neptune's moon Triton, identify blue festoons in Jupiter's atmosphere, and resolve more detail in wispy nebulae. But what about the 130P? It still provides plenty of power for deep-sky observation, albeit with less detail compared to its beefier brother.
So, which one's right for you? If you can swing the cost difference, the 150P offers a more impressive viewing experience, especially when it comes to deep-sky observation. The 130P is a solid choice, too, but you might find the 150P's brighter and more detailed views hard to resist.
Optical Tube & Performance
The parabolic primary mirrors of the Virtuoso GTi telescopes are meticulously polished for sharp images. The 150P's mirror has a focal length of 750mm, compared to the 130P's 650mm focal length. This means that with the same eyepiece, the 150P offers 15% more magnification. The superior light-gathering power and resolving power of the 150P make it the preferred choice for those who want to observe subtle details in deep-sky objects.
The Virtuoso GTi's open-tube design reduces concerns about cooldown or tube currents impacting performance, and precise collimation is essential for sharp views with any Newtonian reflecting telescope. Cooldown time is minimal due to the telescopes' small size and thin primary mirrors.
The focuser on both models is a simple helical unit, accepting 1.25" eyepieces. The 10mm eyepiece that comes with the telescope offers 65x/75x magnification, but it might be worth investing in a shorter focal length eyepiece for higher magnification, like a 4mm planetary eyepiece or a 6mm redline/goldline.
Mounting
The Virtuoso GTi uses a tabletop alt-azimuth fork mount, which handles just as well as any manual alt-azimuth mounted telescope. Clutch knobs on the altitude (up/down) and azimuth (left/right) axes enable manual aiming. The mount is designed to be used primarily when powered on, with the synScan app handling control. The SynScan app offers multiple alignment options, including level-north, 2- and 3-star alignments, or using the Moon or a planet. Unlike many tabletop Dobsonians, the Virtuoso GTi can be mounted on a tripod, adding to its portability.
Astrophotography
The Virtuoso GTi telescopes can be used for astrophotography, but keep in mind the inability to use a coma corrector, and the mechanical play in the 1.25" helical focuser may limit your choice of camera. For deep-sky imaging, you'll want a high-sensitivity camera and a laptop with plenty of RAM, along with at least a terabyte of storage.
Planetary imaging requires a 5x-that's right, 5x-Barlow lens to boost the telescopes to an f/25 focal ratio, along with a suitable planetary camera. Any sort of astrophotography is best conducted with the bottom of the mount attached to a heavy-duty tripod to prevent wobbling or displacement during the imaging session.
