it won't be your only purchase, that's for sure.
So true. I started out with binoculars to "test the waters" and see if I would actually like astronomy. It wasn't until the Total Lunar Eclipse on Dec 21st, 2010 that I realized I really wanted a telescope. I talked myself into an Omni XLT 102 after a while, and I learned a LOT with this scope. I learned that I am very sensitive to CA. I also discovered how fun the pursuit of the Messier objects are, so I bought a 10" Dob. Then comes the filters, the eyepieces, the solar film for my refractor. As you discover your habits and favorite objects, you'll begin personalizing and buying to fit your needs. After all I have, i'm now in the market for a 4" APO for Grab and Go and quick peeks; there's always something to buy.
