Most of the moon and planet images was taken with a Celestron 14 inch SC telescope in the prime focus, using webcam technique and "lucky imaging" with different cameras from "The Imaging Source" TIS (DMK 21/31/41), Celestron SkyRis and later ZWO ASI 290. The SC telescope is a standard C14 and relatively old, but of very, very high optical quality.

Some images are taken with the Zeiss 6" APQ telescope using the same image recording technique.

In the year 2015 we started a bigger, special moon project and within 3 months we recorded the raw material for 2 extensive moon atlases.

The first atlas exclusively shows lunar volcanic structures, the second atlas shows Craters, groove systems (rills), garaben, hills, mountains and mountain slopes. The more than 500 moon images correspond to the Best category with an image resolution between 1,000 and 2000 meters. The best images show details < 1,000 meters.

The first atlas is divided into 21 segments and shows the volcanic structures under different lighting conditions. The second atlas shows the normal lunar structures in increasing moon age from 3.3 to 13.1 days. These two lunar atlases form a self-contained section of the Chameleon Observatory Web.

Extensive texts describe the individual structures in detail. Due to the large number of images and individual websites, both lunar atlases are opened in a separate browser window. They are a completely separate area within our Chamaeleon site.

For many other moon images, which are published on our website the following terms are ...
We are marking the quality of our images (subjective) into four classes, which can be found as colored little squares or circles in the overview images. More information about image acquisition- and processing here.

Standard Good +/- Best Favorite
  • Standard is the picture quality we are almost always able to reach with the C14/Zeiss APQ at Onjala,
  • Good is a better picture quality, but during recording of the avi file obvious seeing differences are still visible.
  • Best is a picture quality, where the C14 - in the focal recording mode driven with the DMK 31- gets close to the limits of theoretical resolution ( e.g. more than 4 craterlets on Plato, details in the Vallis Alpes rille) .
  • Favorite are the pictures we like the most. Most of these pictures have very high resolution, although that's not a necessity. Often these are pictures which show a region that is rarely recorded, have special lighting conditions or show special objects. In most of the pictures though, all of this is true.
