This is a great program and the physics and math required is picked up along the way. The teaching staff and other students are very helpful if I have any questions and I am also picking up some of the math and physics needed on my way. The Major Projects are all research-based units. To do anything professional (assuming one could actually find a position) one would need to go on to a PhD program, and there are Swinburne Graduates who have done so quite successfully. There are jobs, as you point out, for which an MSc (Astronomy) would be perfectly adequate. I was medically retired in 2011, so my own study is just to keep my brain working and for the pleasure of it! Thanks for the reply.

I enrolled in Swinburne University's Astronomy Online course a couple of years ago and have found it to be terrific. You can enrol in a Graduate Certificate, Graduate Diploma or the Master's degree. You can study one subject per semester, which would fit into your 10 hour p/w time allowance. I have no real background in mathematics or physics, but I'm finding the course more than manageable, and the staff and other students are really helpful.
