Hello, I am new to this forum and would like to get some information regarding astrophotography. I have a Nikon D3200 with 2 lenses (55-200mm and 18-55m). The lenses came bundled with the camera, so I'm guessing they are very beginner-level (which has been OK so far) Here are my questions (with apologies if they do not make sense): 1) Are these lenses sufficient for astrophotography or do I need to get a better lens? 2) If I need to get a better lens, what should I get: a zoom lens or a fixed lens? 3) If I am going to take pictures of the Milky Way or of planets and stars, do I need an equatorial mount? If not, how can I counteract the east-west motion of the earth during long exposures? Regards
