Use the above link to the interactive sky chart, select Ang Mo Kio as the city and Singapore as the country under "World By City" and submit

I am pleasantly surprised the interactive sky map knows where Ang Mo Kio is.

Yeap, it seems to know every major place in Singapore. Enter Tuas, it is at 1deg19'N 103deg39'E, Changi @ 1deg21'N 103deg58'E and Toa Payoh @ 1deg20'N 103deg51'E.

Wow, amazing! Apparently these American software engineers are smarter than I thought, i.e. they know Singapore isn't part of China

A bit too late, but here is a good article about how to use a sky atlas:

We don't have an RA. Only astronomical objects have a RA coordinate. For geographical coordinates we use latitude and longtitude.

I'd suggest that you bring along your star atlas to one of the ob events and consult the gurus there. I'm sure many of them will be happy to teach you how to use it.
