I'm looking to purchase some Baader eyepieces and filters. Bang for buck what ones would make a nice set? I would like to get four and some 2" filters to boot. Opinions welcome! thanks

Hey, Billy. I have six Hyperions...
3.5, 5, 8 13 17 and 21mm. I use the 8, 13, and 21 most frequently. The 3.5 rarely, but when seeing allows it works well. All have a nice wide field. The color correction is good, but not spectacular, especially at the field edge.
As for filters, these eyepieces (when used in their standard configuration) would use 1.25" filters. The design allows them to fit either 1.25" or 2" focusers. The 1.25" barrel can be removed (along with the field lens) making the eyepiece longer in effective focal length, widening the field, and requiring a 2" filter. The edge correction in the "wide" configuration is not as good, and I rarely do this.
