Re: (IAAC)Object:- Cat's eye Nebula 20" Dob-Newt

Very intriguing post, NJM! I enjoyed the fact that you posted both a finding 
technique for beginners, and some real details for those who might want to give 
the Cat's Eye another look. BTW, apropos an earlier thread, how did you find 
the UHC filter changed the appearance of this weird planetary? I'd expect some 
intriguing differences in emission patterns from "normal" planetaries!
Clear skies all!
