Hi everyone
I have been interested in taking up something Astronomy related as a career for quite a while now, and after doing a search on this site, I discovered a lot of good information about universities offering online degrees.
I have been studying astronomy/maths/physics in my spare time for over a year now and I love it, and I consider myself reasonably knowledgable in all of these areas. I have a decent amount of hands on scope experience as well.
Universities such as Swinburne and JCU offer Masters courses. Recently I applied for the Swinburne Grad Certificate, but unfortunately I was knocked back because I do not have an undergrad degree

. It was a bit of a longshot hoping to get in, but I thought maybe my prior experience might get me in (provided they believed me

).
So I should get to the point. I have a couple of questions about how I should pursue this and I'm hoping somebody out there can give me some advice. Any advice is appreciated.
What undergraduate degrees should I take a look at in order to eventually attempt a higher degree in Astronomy? Ideally, it would be an undergrad astronomy degree, but i'm not sure if that is possible. Would maths/physics be a good path to take?
I should mention that I am looking for an online course so it doesn't necessarily have to be an Australian university. Has anybody done any undergrad degrees online that are related to what I am after?
I apologize that I have not made a proper introduction on the forums and that I may come across as demanding and lazy. I am a little bit demoralized about my Swinburne application being declined and I am a little bit stressed about the small time frame that I have to apply for courses as the first semester starts very soon, so I am chasing information quickly. I am searching for information on google trying to find some relevant courses but I am not having much luck with Australian online universities. I am hoping that people with a bit of experience with these kind of online courses may be able to provide a little bit of guidance.
Thanks
