The Planet Saturn on 05-28-2015

The Planet Saturn reached opposition last week, weather had kept me from imaging it then.  I managed to grab a shot between T-Storms last night…the Atmosphere was boiling….considering the Poor seeing Conditions, It turned out okay! Look for Saturn between the Constellations of Scorpius & Libra, near Delta Scorpii, High in the South East by Midnight. Any small telescope with at least 30x power will show you Saturn’s Rings.  Now is a great time to Observe Saturn!!!

The Planet Venus in Ultra-Violet Light!

The Planet Venus – Digging out details from Earth’s Evil Twin!
In the telescope Venus appears as a “Bright” featureless planet except for its ever changing Crescent to Gibbous Phases. Venus is shrouded by a dense cloud layer of sulfur dioxide and sulfuric acid that reflects most sunlight back into space, which creates a ‘greenhouse effect’ and hampers direct observation of the planet’s surface. So when I look through my telescope unlike Jupiter or Saturn, I can’t make out any features in the Cloud tops, until I tried an Ultra-Violet filter!
Venus’ clouds have markings that are light and dark in the ultraviolet range. Venus has a 800F + surface temp, so the UV stripes are likely from Volcanoes pumping a chemical high into the upper atmosphere, this chemical absorbs UV light making for dark and light patches on the Cloud tops.
Now I can see football stripes – cloud features on Venus. Seeing wasn’t the best but I got some details in the cloud tops! At its farthest, Venus lies 162 million miles (261 million kilometers) away. It makes its closest approach to Earth about once every 584 days, when Venus & Earth catch up to one another. On average, it is 25 million miles (40 million km) away at that point.
