In 1974 the Radcliffe Observatory telescope was purchased by the CSIR and moved to Sutherland, where it recommenced work in 1976. The Republic Observatory, Johannesburg, was merged with the much older Royal Observatory, Cape of Good Hope in January 1972 to form the South African Astronomical Observatory. The post of Her Majesty's astronomer at the Cape of Good Hope was awarded the Royal Medal on two occasions the first to Thomas Maclear in 1869 for measurement of an arc of the meridian at the Cape of Good Hope and the second to David Gill in 1903 for researches in solar and stellar parallax, and his energetic direction of the Royal Observatory at the Cape of Good Hope. Construction of the main buildings was completed in 1829 at a cost of £30,000 (equivalent to £2.8 million in 2022 ). The history of the SAAO began when the Royal Observatory at the Cape of Good Hope was founded in 1820, the first scientific institution in Africa.

PDF Editor & Viewer Master PDF Editor has almost all the same features as Acrobat.

Try Master PDF Editor, free for personal use, very affordable price in case you need to go commercial. If you need to be able to fully edit multiple page pdf document(move/remove existing images inside the page, edit existing text etc.) and do it more convenient way than Inkscape+Pdf arranger method, I can only recommend a proprietary(a.k.a. The price and the licensing terms are VERY attractive. Currently my personal choice when it comes to complex PDF editing. Try PDF Master Editor (free for non commercial use). PDF form tools for Linux (Acroform or XFA) I usually install masterpdf5 via Flathub for convenience if I don't need to do major edits, and use masterpdf4 for major edits only (installing masterpdf5 on Flathub meant the two versions doesn't interfere with each other's settings). If you need the editing features, use masterpdf4 (also on AUR).

Have you tried Master PDF? It's on Flathub too.
