SkyWatcher 150/1200 is a mirror telescope system Newton with a mirror diameter of 150 mm and a focal length of 1200 mm.
It allows to conduct very advanced visual observations of planets and the Moon, showing a large amount of details on the surfaces of these objects. Due to its construction, it is also recommended for observing nebular objects. Under good observational conditions, it can reveal hundreds of nebulae, galaxies and star clusters included in the Messier and NGC catalogs. It also has a built-in focuser with a diameter of 1.25 inches, which allows the use of any glasses made in this standard, and the integrated thread T2 allows you to attach a reflex camera (camera with interchangeable lens). The whole is a perfect solution for both beginners and advanced observers, guaranteeing a very competitive price.
The telescope's EQ3-2 paraglider montage is a recognized quality that guarantees high stiffness, enabling observation at high magnifications. The light, adjustable height aluminum stand is easy to carry and at the same time stable, while the accessory shelf and the precise micromovement mechanism on hand-operated scrolls complete the set.

This device focuses a lot of light. Looking directly at the sun through this device can result in partial or complete loss of vision. For the observation of the Sun, we recommend the safest method of spectacle projection, that is, projecting the image of the target of our day star on a piece of paper.

Due to numerous questions about the choice between two very similar models, differing focal length, below a few comments and hints for thoughts.
Sky-Watcher N-150/750 EQ3-2
• a shorter focal length is a brighter image in the focus - when taking pictures of the deep sky (nebulae, galaxies) we can get a clearer picture with the same exposure time compared to a 1200 mm telescope
• shorter focal length means less vibrations of the assembly - important for long-term exposures
• shorter focal length in Newton's telescope means easier transport (shorter tube)
• SK 150/750 EQ3-2 is equipped with a 2 "lift with reduction to 1.25", SK 150/1200 EQ3-2 with a lift of 1.25 "
• shorter focal length is the larger secondary mirror (higher light loss, slightly lower resolution
• the telescope is more sensitive to collimation imperfections and prone to "losing" collimation
Sky-Watcher N-150/1200 EQ3-2
• longer focal length is a smaller secondary mirror, consequently higher resolution, better images of the Moon, planets and globular clusters
• longer focal length means larger planet sizes on the matrix when shooting at the main focus (with Barlow or without)
• usually better results are obtained when we want to set in the telescope a large magnification, when we have a longer telescope focal length and longer focal length of the eyepiece, than by using an extremely short focal eyepiece in a short focal telescope (including a better eye relief )
• longer focal length ensures easier collimation and less susceptibility to "losing"
• the telescope is not intended for longer exposures of deep sky objects in the main focus, either because of the lower brightness in the main focus, as well as the potentially greater vibrations of the assembly (although it may be well-suited when photographing "piggyback") from piggy-back )
The above notes are applicable not only to the above-mentioned models, but may serve as a guide when comparing other telescopes with analogous parameters (eg N-203/800 vs. N-203/1000, N-130/900 vs. N- 130/650)
