Please invest on classes that teach you how to hold a camera instead. Ruins the video.

I like dreaming about space but the least likable part of amateur astronomy is how the learning curve levels out after just a few weeks of self study. The basics of astronomy and optics are repeatedly explained. Every tour and every star party is filled with the same old basics. How many times do they have to say refractors use lenses and reflectors use mirrors?
