Hi all,
In my opinion, everyone here on IIS who contributes their astronomical observations, expertise or knowledge through posts, articles or photos is contributing to real science. We educate each other here and also foster interest in the field of astronomy. The expanding numbers here on ISS shows that we are succeeding in spreading this interest.
One thing I've found is that professional astronomers aren't always the best people to explain their field. Often a lucid contribution by an amateur will explain things in terms more palatable for general consumption. And amateurs can discover new things or make connections that haven't been notice before.
So just contribute!
If you want to go into a specialist field like variable star observing, supernova hunting or occultations, by all means do so.
Regards, Rob
