Sky-Watcher EvoStar 90 EQ2
90mm 3.5" 900mm Refractor Telescope
Sky-Watcher EVOSTAR telescopes are classic two-element, air-spaced, achromatic refractors. They are outstanding, high-performance, high-resolution instruments manufactured to high standards of optical and mechanical precision.
With their long focal lengths and breathtaking, diffraction limited optical performance, they are ideal for the detailed high-power study of the Moon, Planetary Surfaces and other objects in our solar system, giving crisp contrasty images. Supplied with the EQ3-2 equatorial mount, which when polar aligned, will allow you to easily track objects as they move across the night sky via its slow motion control cables.

Economic way of owning a simple non-powered small aperture German equatorial casual astronomical telescope. An ideal white light solar refractor by adding some Baader Astrosolar over the front aperture. A low cost instrument for schools to purchase for science project solar observing. Add a simple RA motor for tracking.
Budget for an A4 sheet of Baader Astrosolar and a weak sky pollution filter such as the Baader Neodymium 1.25 filter. Budget also for a 1.25" Baader polarizing set or a 1.25" Neutral density filter for the moon.
