It’s summer in the southern hemisphere and Bruno Yporti, in Londrina, State of Paraná, Brazil, had great weather for imaging last Sunday’s Total Lunar Eclipse of the “Supermoon” over the Americas. At his private, roll-off roof, “Ophiuchus Observatory”, he readied his Tele Vue-85 APO refractor with Tele Vue 2x Powermate and Canon 6D DSLR on an Atlas EQ-G mount for the event. The sky was clear, with almost no wind, when he took the above single exposure — about 10-minutes after the Moon completely entered the inner part of Earth’s shadow. In this phase of the eclipse, the Moon was illuminated by the refracted light skimming along the entire circumference of the Earth. The deep-red light bathing the Moon is what we see at sunrise and sunset on the horizon.
Sky watchers are in for a double-treat with lunar and planetary events on the schedule in the next few days. Brilliant Jupiter and Venus dazzle in the morning as the planets approach conjunction. Sunday night in the Americas will be dominated by the total lunar eclipse.
The premier event of 2019 awaits the end of the year when Mercury appears to pass over the face of the sun (as seen from Earth) on November 11th from 12:35 to 18:04 UT. Due to its diminutive size — only 10-arc-seconds in diameter — eclipse glasses over your eyes will not do: you’ll need a properly solar filtered telescope, binocular, or telephoto lens to view it (see Viewing/Imaging Resources at bottom). Don’t miss it as the next transit of Mercury won’t be until 2032.
Tele Vue founder Al Nagler was one of 400,000 people estimated to have worked on the Apollo moon landing program. The year 2019 marks the 50th anniversary of the culmination of all that effort: the first manned Moon landing. Al’s involvement with that mission and derivative work for the Air Force during that period would inspire him to found Tele Vue Optics and influence our eyepiece designs for decades to come.
