Anis Abdul’s composite image of Uranus and moons is from the October 2017 opposition and was posted to his Facebook page. The imaging gear used was a Celestron Edge 11 telescope, riding on on AP900 mount, that was “amplified” with our Tele Vue 2.5x Powermate to achieve 7,000 mm focal length. Imaging was done with a ZWO ASI224MC color camera . The best 50% of frames from 20-minutes of video were processed for the image. Software used was Pixinsight and Registax.
“One of the closer moon (Miranda) is actually visible in my stacks but is lost in the planet glow ,” says Anis.
The “ice giant” planet Uranus was in opposition on October 28th. That means that the Sun, Earth, and Uranus all lined up together at an instant in time on that date. Uranus is on the same side of the Sun as the Earth, so the planet was closest to Earth and brightest for the year and in the sky all night long. If you missed it: don’t worry. The slow-moving planet will remain at least 3.7″ of arc in diameter and at magnitude 5.7 for the next month.
What I like about star parties is meeting and speaking to all the fine people that travel long distances for great observing experiences. Sometimes the conversations continue after the event. This is an excerpt from a note I received from Bob Danko, of Warren Ohio, soon after returning from the Cherry Springs Star Party this June.
