Literature on transmission to the Christian world:
Alphonsine treatises (written for King Alfons X of Castilia, ca. 1250 CE): manuscript of the Libros del Saber de Astronomia at the Library of the Universidad Complutense in Madrid is available online, p. 157 is approximately the beginning of the part on the Universal Astrolabe.
Alphonsine books: Edition by M. Rico y Sinobas, Libros del Saber de Astronomia del Rey D. Alfonso X de Castilla, vol. 3, Madrid 1864.
Download vol. 3, the two parts (by clicking on the images). The first part contains the preface by Rico y Sinobas plus p. 1-234 of the editions:
p. 1-132, Libros de la Lamina Universal, , the first book (p. 1-10 with nice pictures) is by Rabicag, the Libro Segundo (p. 11-132) is by Ali ibn Khalaf.
p. 133-234 plus 235-237 Libro de Acafeha by Azarquiel (pictures on p. 143 of the back side with the orthographic projection; between p. 147 and 149 both sides of the Zarqaliyya plate). The second part includes the last two pages of al-Zarqalluh's work plus a treatise on equatoria which does not concern us here.
Volume 3 was reprinted in F. Sezgin, Islamic Mathematics and Astronomy vol. 111, Frankfurt 2002.
Pseudo-Mashallah (author identified as Maslama al-Majriti by Kunitsch), The astrolabe by Messehallah (Latin manuscript and text, with English translation) printed in Gunther, Early Science in Oxford, vol. 5, Oxford 1920., pp. 137-231. Download in pdf or other formats(archive.org). The same volume 5 contains on pp. 1-136 the treatise on the astrolabe by Geoffrey Chaucer (ca. 1340-1400).
Note that Gunther's translation of the text by pseudo-Mashallah contains many errors, because Gunther did not understand all the details of the construction of an astrolabe.
