Description

In March 2019 I posted my Analemma project where I used a pinhole camera with a rotating slit mask  Pinhole CameraPinhole Analemma 2018/2019
Now I have set up an electronic version using a DMK-camera with a small wide angle objective. To reduce the brightnesse I placed a small piece of Baader Solar foil between the objective and the sensor chip. The pictures are taken by an Raspberry PI4 together with the EKOS KStar software. The pictures of the sun are taken with 2ms exposure time in an interval of 20 minutes over a period of about 7 houres during daytime. The stacked pictures are merged together with a colour photo taken at the beginning of the experiment. The first quarter of the Analemma runs from summer solstice to autumn equinox.
