Ken what I'd do is put Glen's original data in an Excel spreadsheet, then using his decimal RA column as the reference field add the extra cells with formula as above, then simply copy and paste downwards from there to add the formula with new reference field to each line of data .....
Ah forget it - here it is, completed
2 files - one has converted RA(decimal) to Hrs & Mins, the other converted to Hrs, Mins & Secs.
Hope you find it useful!
