I think Treadmarks may have a very valid point here. I have not been in the habit of using filters throughout my 40+ years of amateur astronomy. I never liked the artificial effect that color filters created despite perceived contrast improvement in some cases. I have also been delinquent in using my crossed polarizing filters. My eyes have always been light sensitive and I started wearing very dark sunglasses outdoors in my early 20s. Living in Arizona now makes it a must. I am 71 now, and luckily my last eye exam several months ago showed no trace of cataracts. I do remember feeling that the glare produced by an 8" scope on Jupiter was a bit uncomfortable, but I don't remember ever trying a filter. I must admit that Saturn always looked good in the larger SCTs but Jupiter seemed to be the detail/contrast problem. I do remember decent views of Jupiter in a friend's C-5 but never thought about it seriously. I now use a 6" Mak for planetary and it has given me the best views of Jupiter I have ever had. Maybe I need to get another C-8 or C-9 and "dust off' my polarizing filters. I do agree with Bataleon w.r.t. Maks and the majority of DSOs, but planetary viewing, double stars, and carbon stars have been my interest for the past 10 years.
Thanks for the comments!
