Fellow IISer,
hickny, aka Peter, has come up with an algorithm that converts celestial co-ordinates to alt-az ones using a programable calculator. His working calculator also has the entire NGC catalogue programmed into it, so he just inputs the local time (local geo co-orda preset) & the object u want, & it spits out the alt-az co-ords for you.
There are also little gizzmos that work on producing alt-az co-ords when for when the scope is moved, much like the apps for phones that measure angles. The specific one I'm thinking of name escapes me, bugger! But Peter's also got one that he's used to guide his scope. Works bloody well too! Maybe drop him a PM. I'll let him know about this thread too.
Mental.
