Star Cross-Reference Data For LX200 Users

I have a 10" LX200 Schmidt-Cassegrain telescope manufactured by Meade Instruments Corporation in the USA. It is a wonderful instrument that gives me superb views of the heavens - or at least as superb as you can get 10 miles from the centre of London in the UK on those rare ocassions when it's not cloudy!

I got an LX200 because, among other things, I wanted the GOTO feature; I want to spend my rather limited observing time looking at objects rather than for them. Unfortunately most authors tend to refer to stars using their conventional names or references (including Bayer letters, Flamsteed numbers and GCVS references) rather than their SAO, GCVS or Meade STAR numbers. I have spent considerable time cross-referencing these names and references against the LX200 databases so that I can easily convert the references I encounter into numbers my LX200 can understand. For example:

Conventional Reference LX200 Reference
Aladfar SAO 68010
CF Boo GCVS 90107
eta Cyg SAO 69116
18 Dra SAO 106712
P Eri STAR 260

It's a lot easier punching numbers like these into the LX200 keypad than star hopping using a dew-sodden chart in a disintegrating magazine by red torchlight!

I want to share the results of this work with other LX200 users, so I have produced tables that can be browsed here on my web site. There are 3 tables for each of the 88 constellations - one listing Bayer letters and Flamsteed numbers, one listing GCVS references and one listing SAO numbers not included in the first 2 tables. There is another table containing an alphabetical list of star names, and 4 more tables for looking up SAO numbers directly. Please note that some entries you might expect to see may not be there because I have stripped out all references to stars that the LX200 doesn't know about. Please also note that I encountered many discrepancies while putting these tables together, and where different sources are inconsistent I have taken views about which sources are correct. It's pretty unlikely that I made all those decisions correctly!

You can download the entire data set as a (WinZip compressed) text file with fields delimited by semi-colons. There are nearly 37,000 rows of data, so please be aware that because of the 16K maximum row limit in Excel 95 you won't be able to load it into an Excel spreadsheet unless you have Excel 97 or later.

I got all the information I needed from NASA's excellent Astronomical Data Center web site, who permit their data to be used and re-published as long as you credit them for providing it - which I do gladly.
