Hey guys!
Just wondering if I wanna do some deep sky observation (i.e. Star Cluster, Nebulae etc) But I got some questions that wanna ask:

What do I need? Some filters? What type of filter do I need?

With the aid of the filter, is it possible to get the pretty colorful nebulae image?

What the size of the eyepiece do U guys suggest? the small one or the large one?
Many many thanks!!!!
