Just got my shot to complete the
comparison of the full moon at perigee and apogee (or at least fairly close to those times). Each image is a stack of exposures processed in Registax, all taken with the same camera, lens, and 300mm zoom, and at 100% crop to preserve the image size directly from the sensor.
The distance and angular diameters listed are calculated by emphemeris in Virtual Moon Atlas. The predicted ratio of diameters is 1.137. By pixel measurement in Gimp, I calculate a ratio of about 1.15. Pretty good agreement, and I'm not sure what might account for the discrepancy except that perhaps because it is a zoom lens I did not achieve precisely the same focal length.
Besides the obvious difference in size when compared side by side, I think it's also pretty neat to see how the Moon
wobbles. This allows us to see quite a bit more than just 50% of the Moon from the Earth.
