rockystar Posted November 17, 2016 Share Posted November 17, 2016 what format do you want it in? It's available here ftp://cdsarc.u-strasbg.fr/cats/I/131A/ but it's in .dat binary format which you would need to read with a computer program (the documentation gives the byte markers) Link to comment Share on other sites More sharing options...
wookie1965 Posted November 17, 2016 Author Share Posted November 17, 2016 I would prefer to have it in text so I can just read it wouldn't know what program to use or how to run .dat files. Link to comment Share on other sites More sharing options...
cotterless45 Posted November 18, 2016 Share Posted November 18, 2016 Sky Safari 5 Pro gives SAO numbers of stars . In addition you can enter an SAO number to get details, sky location, history etc. There are also a lot of other reference details included in this app. It's a most beautiful complete app. In addition should you wish to guide your scope wirelessly , you'll be free of the limitations that your goto handset has in regard to the SAO catalogue, old Nick.

faulksy Posted November 18, 2016 Share Posted November 18, 2016 just like nick says, this is the best app ever, it lists everything out there, gives you specs on it, images of it and controlls your scope, this is what i use with my nexus dsc Link to comment Share on other sites More sharing options...
cotterless45 Posted November 18, 2016 Share Posted November 18, 2016 There's the Sky 2000.0 book ,but from £60 upwards for volume 1, the Sky Safari pro app is far better value and use, Nick. Link to comment Share on other sites More sharing options...
ronin Posted November 18, 2016 Share Posted November 18, 2016 There is this catalogue: SAO-KPNO But it is just a list of SAO + (RA+Dec) and a few items, equally that may be all the SAO ctalogue is. It is ordered by RA, so the actual SAO numbers are scattered. Should be fairly easy to make a table of it then order by SAO Number. You would in the simplest form need to Select all (Ctrl A), then copy (Ctrl C) then open a text file and paste (Ctrl V). Then you can play, safer to make 2 copies if you play. Looking at it I guess it is a list of proper motion (???) and it also provides the spectral class in about half - not sure as all I have looked at are the first few pages. As an aside the Gaia data may well provide better proper motion data if that is the primary reason. Tne BAA also say that catalogues are available at CDS, but whatever method CDS use to file their catalogues as I cannot locate the SAO one, I suspect that it is there somewhere, so perhaps 10-15 minutes could be useful.

I just downloaded the sao.dat file. .dat format just stands for data as I understand (& use) it. Rename it as sao.txt if you want or you can just open it as a plain text file in any text editor (emacs works fine for example). Line 1 contains: 1 0 0 5.097-0.0083 4 5.636101885.1+824141.82+0.002 4 41.70121887.1 2699.9 7.2A0 14 101000070 3BD+82 748 2250190 30.00037068 1.44329914 0 241.650-0.0097+825823.52-0.0040.01175552 1.44815553 with the contents described in the Readme file.

rockystar Posted November 18, 2016 Share Posted November 18, 2016 I didn't download it, I just expected it to be a binary file Link to comment Share on other sites More sharing options...
Putaendo Patrick Posted November 18, 2016 Share Posted November 18, 2016 The catalogue was originally published in four volumes in 1966, with a second edition I think in the 1970s. You may be able to pick up a second-hand copy - check out https://www.abebooks.com/servlet/SearchResults?sts=t&tn=Star+Catalog%3A+Positions+and+Proper+Motions+of+258%2C997+Stars Link to comment Share on other sites More sharing options...
