I don't know how useful this Excel spreadsheet might be as I have searched and can find nothing similar. Anyhow, it calculates real-time Alt and Az for a number of Messier objects which I find very useful for Dob type telescope pointing. All you need input is your location (lat/long) and your UT hours difference.
In MS Excel, it uses a little VBA code to do the alt/az update automatically a two second intervals. I have ported it to an Android tablet running its version of Excel but it does not support VBA so one has to do a Calculate Now to get the current values.
Any object can be easily added by copying to a new row and entering the object's name, RA and Declination.
Tried to post this but got an error: "You aren't permitted to upload this type of file"
Is this because it's a spreadsheet or maybe a spreadsheet with a macro??
