Pack Dobson Sky-Watcher Virtuoso Gti 150mm GoTo Telescope with personalized initiation course
IN TELESCOPIOMANIA WE OFFER YOU NOW TOGETHER WITH YOUR TELESCOPE, OUR PERSONALIZED COURSE OF INITIATION IN ASTRONOMY AND USE OF YOUR GOTO TELESCOPE.
The Virtuoso 150mm GTi combines 2 important elements:
- Great observing comfort (the instrument finds objects in the sky for you to observe and compensates for the apparent motion of the stars due to the Earth's rotation).
- Like the other Heritage models, it is extremely compact, folding in on itself. It is perfect for traveling.
This patented innovation (FlexTube) saves space, ease of use and time. There is no need to disassemble and reassemble the instrument each time it is used, as is the case with conventional Dobson scopes. The same is true for collimation: once set up for the first use, there is no need to do it again for each observation. In fact, the structure supporting the secondary mirror slides into the primary mirror cage by means of two rigid rods, without the need to adjust the secondary mirror with respect to the primary mirror.
With a 150mm primary mirror, the Sky-Watcher Dobson 150mm Virtuoso GTi is a great way to get started, thanks to its ability to collect 73% more light than a 114mm telescope. Under dark skies, you can discover your first nebulae or globular clusters (the brightest objects in the famous Messier catalog). You will be able to locate them and, in the case of the Orion nebula, for example, see many details. In summer, with the majestic Milky Way (our galaxy), you will be able to see as many objects as possible.
For beginners who wish to invest in a telescope that is both bright and inexpensive, it promises many afternoons of very rewarding observations. In planetary observing, after collimation, it will reveal many details of Jupiter, Saturn and the Moon, using a Barlow or short focal eyepiece.
Design
Its Newton-type design offers several advantages over other families of instruments (Cassegrain telescopes and spotting scopes). First, the mirrors are cheaper to manufacture for the same diameter, and the focal ratio is generally lower (hence shorter focal length and larger field with the same eyepiece). This results in a bright telescope for an attractive budget. The central obscuration is also lower than in Cassegrain type telescopes, and if the collimation (mirror adjustment) is done correctly, the image quality is good for planets.
Unlike the very inexpensive models, the Newton (Dobson) SkyWatcher telescopes have a parabolic primary mirror. Initially, the mirrors are spherically polished and then reshaped to achieve a paraboloidal shape (more expensive and difficult to obtain). This is an essential selection criterion for instruments larger than 114 mm and with a short f/D. Beautiful, efficient and practical, the Sky-Watcher 150mm Virtuoso GTi will please you and make you appreciate astronomy.
Sky-Watcher GTi Mount
To expand its range of mounts, Sky-Watcher has been inspired by the AZ-GTi mount for the Mak127 by adapting it to a rocker (the structure used on the Dobson). This GOTO (automatic pointing) mount is therefore an altazimuth mount (the simplest, most convenient and versatile system to use), with 2-axis motorization and its own WiFi network. Use your smartphone (with Google Android or Apple iOS) and the free SynScan app to control your mount wirelessly.
After entering the coordinates into the app and following the simple alignment procedure, you can explore the Universe with your smartphone or tablet. No need to know the sky, thanks to the database of more than 10,000 objects... and the dual-axis motorization means you won't have to manually compensate for the Earth's rotation. Virtuoso GTi even lets you, with the help of SkyWatcher Freedom-Find™ technology, move the instrument manually without losing positioning. This gives you maximum freedom, choice and flexibility during your observations.
