Sky-Watcher EvoStar 90 EQ3-2
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.

Budget priced small refractor on a much more substantial mount than the EQ2. The EQ3-2 can be upgraded to RA tracking or even full GOTO. 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.
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.
