As we have previously discussed from 1906 to 1918 Lovecraft’s writings focused heavily on astronomy. He produced a number of articles and documents on astronomical observations, which were frequently published in newspapers such as the Providence Evening News and the Ashville [N.C.] Gazette-News. Additionally, Lovecraft produced reports on the subject but much of this material has never been published and has been lost. However, Necronomicon Press just printed 250 copies of a facsimile reproduction of Lovecraft’s The Annual Report on the Science of Astronomy, 1904. The document includes notes as well as several illustrations by Lovecraft; some of these illustrations are shown below. If you are interested this subject, I strongly recommend you purchase one since they printed only 250 copies.

Do you have any links? Maybe I’m lucky and there’s still one or two available.
Side comment: I like the neat lettering and the drawings.
