Astronomy Equipment Documentation & Supplemental Information


The following are links to manufacturer documentation and supplemental documents written by users. These may be useful to anyone purchasing used equipment or who have purchase equipment with inadequate documentation. These links are weighted towards equipment I own myself, but if you have information worth listing, please let me know about it.


If you have corrections or additional information such as applicability to specific versions of firmware, please drop me a note at: Thank you to all who have contributed this information.

Celestron Advanced Astromaster Digital Setting Circles

This zip file contains two Excel 97 spreadsheets which are the lists of stars and non-stellar objects in the ROM of the Celestron Advanced Astromaster and apparently the Sky Wizard variation sold by other manufacturers (all designed by Tangent). The files included here were modified by me as the fonts in the non-stellar list were messed up as was the print formatting (perhaps this was due to incompatibilities between my version of Excel and another version).
[122K, 19 pages]

[84K, 13 pages]

Adobe Acrobat versions of the above files. SKYWIZ1.PDF is the star list, and SKYWIZ2.PDF is the non-stellar list.

I believe that these lists were originally generated by Roger Steer (Thank you!) in the UK. His downloadable version (Excel 3.0) is at, but the files differ slightly, and the Greek letters in his version of the spreadsheet did not come across properly for me. His files also include an ASCII text version.


Celestron Ultima 2000 Digital Setting Circles

I don't own this scope, but there have been inquiries about whether or not the Astromaster database (above) is the same as the Ultima's database. The answer is that it is not. However, it is available on request from Celestron or from Tom Stamm's web page:
