- No image file from this page is allowed to be used for commercial
or other than scientific or private purposes without the written permission
of Sternwarte Bonn OR

obtained as well. In most cases there will be a fee demanded on behalf
of STERNWARTE BONN, depending
on the total amount of images requested and on the purpose and the
requesting organisation. In case of the intention to use images from this site for
editorial purposes (i.e. in periodicals, books etc., other than scientific periodicals, books, where

- The images can be used for scientific uses, such as publications, without
permission. There MUST always be a reference to the source, that
means the observatory (Observatorium Hoher List) and the author/observer
of the particular image. Images where no specific author/observer is stated on the
GALLERY-PAGE are by M. Altmann. Usage of any image will not move the copyright
to any other institution, such as a publisher. Please make sure that is the case, beforehand.
- Personal use (Screen background, prints etc.): free.
Use on personal homepages is free, however mentioning the source (i.e.
author/observer AND institution (observatory) is obligatory. Links
to an image or homepage are of course without restriction.

compulsory, grant will we given depending on the nature of the organisation.
No permission will be given to extremist or dubious organisations.
Normally the fee will be waved.
