Orion AstroView 90mm EQ Refractor
A 90mm achromatic refractor on a proper equatorial mount, positioned well above toy-store refractors. The 910mm focal length at f/10.1 is well suited to lunar and planetary observation with a modest budget. The equatorial mount introduces the observer to polar alignment and makes Saturn tracking more intuitive than an alt-az platform. Sharp, colour-correct views for the aperture. A classic first refractor for the careful buyer who wants the refractor experience with a proper mount underneath it.
