Hello, I'm currently in the process of purchasing a Celestron Nexstar Evolution 8 and I have several questions.

1. Does it require maintenance? If so, what tools would best be used? I've seen laser collimators and collimation knobs. Will I need these things?

2. Dew control items such as dew rings and controllers, and aluminum dew shields.

3. What eyepieces are recommended to best upgrade my viewing experience with this telescope?

Please note I only plan on using the Evolution 8 for planetary and deep space observation only.
