I'm an undergrad in physics and astronomy deciding to look into applying for time on a research telescope, and I'm not sure how to proceed with locating/finding telescopes that I can apply for time on. Specifically, I'm interested in looking at the chemical composition of protostellar disk(s). Any applicable information would be nice.
As an undergraduate, you are a member of a university. Your first step then should be to talk to your Professors.
As a guide to what might be expected, look at the University of Arizona telescope proposal page They accept proposals from members of Arizona University. You have to have a clear aim and plan. This is why you need to talk to your professors first.
