Southern Stars
I'm beginning a new chapter in my variable star work, Since taking an astronomy course at GTCC in 1997 I've been making visual observations of variable stars for the AAVSO. I haven't done many, but a few every year usually get added to my records.
This year I'm learning how to take images of the variable stars and calculating magnitude using computer software. In addition, I will be looking at stars in the southern sky, stars unavailable to observers this far north of the equator.
My first target is to calibrate exposure time. I've taken an 80 second exposure of the variable star u tuc. It's found in the constellation Tucana (the Toucan). There are apparently many unknowns about this particular star, including it's distance from Earth and the period of variability.
