Having taken some photos of the last super moon on 10th August 2014 with my Sony 500mm F8 mirror AF lens, I could not wait to take a photo of the next super moon using my telescope. In anticipation of the third of the trio of super moons (July to September 2014) and the last one of 2014, I decided to image the moon from 7th to 9th September ’14, partly to get experience in imaging the moon, and also to see the change in the moon during those three days.
As I have posted before, the mid-autumn festival (aka moon cake festival) fell on 8th September 2014, during the full moon. But according to various sources on the internet, the super moon would be on 9th September, when it is much closer to the earth in its orbit – it is termed a super moon as it is said to be 30% brighter and about 10% larger
Here are images shot from the three nights, but do bear in mind that the 7th September moon shots were taken with a shorter focal length telescope (860mm vs 1200mm) and hence cannot be compared in size to the other two nights, without some serious mathematical calculations. The 7th September shots were cropped to 1280×1280, whereas the 8th and 9th September moon shots were cropped to 1600×1600. I have included two best shots for each night down below.
All were taken with my full-spectrum Olympus E-PL5 and Baader Moon glow filter. 7th September moon shots were using William Optics 72 Megrez APO refractor, while 8th and 9th September shots were taken using Skywatcher ED80 refractor.
On 7th September, you can see there is an area on the left side of the moon which is still in shadow.
Full moon on 8/9/14, which was Mid-autumn festival. As you can see, the moon fills up nearly all of the 1600×1600 crop, with no area in shadow.
You can see that the super moon on the 9th September 2014 now shows an area of shadow on the right side. But is the super moon on 9th September larger? It seems smaller than that on 8th September, just by looking at how much of the 1600×1600 each moon fills up. But perhaps both are larger than a full moon at any other time of the year. I will need to take a photo of another full moon for comparison.
