Should you buy Orion 09007 Observer 90 to observe planets?

The Orion 09007 Observer 90 is an excellent choice for observing planets. It provides sharp, clear views of celestial bodies with its 90mm aperture and 1000mm focal length. Users see Saturn’s rings, Jupiter’s cloud bands, and Mars’ surface features in detail. The telescope’s parabolic optical design minimizes aberrations, resulting in laser-sharp images of small planetary discs. Its high focal ratio of f/11.1 delivers smooth views of planets and allows tracking of objects across the sky. The Observer 90 excels in lunar observation, revealing detailed moon craters. It offers improved optics and a sturdier mount compared to its predecessor, the AstroView series. Buyers should be aware of potential focuser issues and limited performance for deep sky objects like nebulae and star clusters.

Should you buy Orion 90mm Observer Refractor Telescope to observe galaxies?

The Orion 90mm Observer Refractor Telescope is not recommended for observing galaxies. Its limited 90mm aperture struggles to reveal details of distant galaxies. The telescope excels at observing planets and the Moon, providing vivid and sharp images of brighter objects in our solar system. The 1000mm focal length and f/11.1 focal ratio are optimized for planetary viewing. The telescope’s compact size, easy setup, and low maintenance make it suitable for beginners interested in lunar and planetary observations. Galaxy enthusiasts should consider telescopes with larger apertures, such as 150mm or 200mm reflectors or refractors, for improved views of distant objects.

Should you buy Orion Observer 90 Refractor for astrophotography?

The Orion Observer 90 Refractor is not recommended for astrophotography. The telescope’s 90mm aperture is too small for capturing detailed images of deep-space objects. Its mount and tripod lack stability and tracking capabilities necessary for long-exposure photography. The cheapened focuser does not provide precise control required for astrophotography. The telescope is better suited for visual observations, allowing users to see some detail on the moon and planets. It functions well as a beginner’s or family telescope with strong magnifying power for casual viewing. Astrophotography enthusiasts should opt for a telescope with a larger aperture, better mount, and more advanced features to capture vivid and sharp images of celestial objects.

Is Orion Observer 90mm Refractor Telescope portable?

The Orion Observer 90mm Refractor Telescope is moderately portable. The telescope weighs 10.5kg and measures 102cm x 18cm x 18cm, making it manageable for short trips but less suitable for frequent travel. Its optical tube is removable from the mount, allowing quick setup and easier transport. Users can carry the telescope components separately, reducing bulk and weight. The removable counterweight further enhances portability by allowing balance adjustments. The telescope’s design enables impromptu observing sessions and short trips to dark-sky locations. The tripod, with a height range of 63-90cm and leg diameter of 25mm, is compact and easily carried. Astronomers can transport the telescope in a car or on public transportation to observe from different locations.
