Both images were taken with the same equipment (Nikon D500 and Tamron 70-300@300m) at two different times. Composite of both images clearly shows us the change in apparent angular size of the moon that is caused by the difference of its distance from Earth at perigee and apogee. The change in apparent size is caused by the Moon’s elliptic orbit around Earth and it amounts to distance difference of approximately 40,000km between both full moon events.
Last week I have attended and helped at the first local Maker Faire event in Ljubljana. This is an event that tries to bring together people or organizations that create things (everything from software and electronics to art and woodwork) in order to promote science, curiosity and knowledge transfer.
In the stands we could meet with the makers from Slovenia and all other neighboring country. Among other things it was apparent that there is a strong motion towards using 3d printers and Arduino platforms as most of the stands showcased a product or idea based on one of them.
The biggest advantage of an event like this for me was a practical aspect of it. There were numerous hands-on activities where you cold try the state-of-the-art equipment, play with different experiments or create your own simple electrical circuit.
