This course is a repeat of a course offered earlier and started on Dec 3.
The 1st homework which is all about
Observational and Visual Astronomy looks quite challenging.

What do the people who attempted it last time think of the course?
Now I've drawn members attention to the course perhaps anybody who signs up could discuss their learning/issues/homework on this or other forums.
I'm just letting people know.
