Options in Venus’ ambiance vary from dusty shadings to shiny spots. You could possibly spot probably the most well-known by means of a #47 (violet) filter and an 8-inch telescope. Search for an immense C- or Y-shaped function centered on the planet’s equator.

For the low-altitude ones, a #58 (inexperienced) works higher. You may also observe morning and night clouds – shiny, remoted patches of floor fog showing at martian dawn and sundown. Night clouds are usually bigger and extra quite a few. For the very best views, use a blue or violet filter.
Observing Jupiter
Subsequent to the Solar and the Moon, the celestial object with the best observable element is the planet Jupiter. Even small scopes present a number of darkish stripes – the North and South Equatorial Belts – flanking the enormous planet’s equator. Watching Jupiter nightly may be rewarding; along with the altering positions of its 4 largest moons, the planet’s rotation brings almost all of its attainable seen areas into view in a single evening. Make sure to goal the Nice Pink Spot!
A #38A (darkish blue) filter will improve the planet’s zones. Blue filters additionally sharpen shiny cloud options. a #23A (crimson) filter brings out particulars alongside Jupiter’s equator and sharpens distinction within the main belts.
Observing Saturn
Search for the Cassini Division, a darkish hole between its two brightest rings. Via an 8-inch scope, observe the brightness, coloration variations and, textures of the planet’s rings. Markings on Saturn’s disk are refined. Observe any shiny or darkish spots in comparison with the belt or zone they’re in. From evening to nighttime, these options could change place.
