The attached link will give you the best information on filters. The Prairie Astronomer - From my own experience I would purchase a UHC filter a great general purpose filter. There are many makes and costs - see FLOs website on visual filters - UHC & OIII Visual filters

This will be a good start for your 8" Dob.
