Asteroid FLORA Observation on August 23, 2016

This is only the second asteroid I have ever knowingly photographed – here is the main-belt asteroid called FLORA. A main-belt asteroid is simply an asteroid found in the main asteroid belt between Jupiter and Mars.

I photographed the same region of space after 50-minutes and combined the images to make the animated GIF showing how Flora moved over this time period.

Tech Specs: Meade LX90 12” telescope, Antares Focal Reducer, and Canon 6D camera all mounted on a Celestron CGEM-DX mount. 2-minutes of collected data using 15-second subs at ISO 3200. Stacked in DSS and refined in Corel Paintshop Pro.

Asteroid PALLAS Observation on August 22, 2016

My next target for the evening of August 22, 2016 was the asteroid Pallas, this is the first asteroid I have photographed. At the time I took the images, I had no idea if it was centered or not, luckily, it was on the upper edge of the frame. For comparison, I selected the same piece of sky from the Sloan Digital Sky Survey (www.sdss.org), you can clearly see Pallas in my image compared to the SDSS image.

I found this interesting graphic in Wikimedia showing the sizes of the first ten Asteroids to be discovered compared to the Earth’s Moon, all to scale. The objects, left to right are: 1 dwarf planet Ceres, 2 Pallas, 3 Juno, 4 Vesta, 5 Astraea, 6 Hebe, 7 Iris, 8 Flora, 9 Metis, and 10 Hygiea.
