Sight reduction- Spreadsheet - LouisC - 12-23-2015
I'm lazy and sometimes am not inclined to work with paper-and-pencil so I use this spreadsheet;
Sunsight reduction spreadsheet
I put the program on my cheapy tablet and get Ho, Hc, Zn and Int. fast.
It can be used to determine any needed figures for the Sun.
Such as;
-Sunrise (UTC)
-Sunset
-MP
Very handy.
