My google search did not turn up anything else in 32mm except Wed, 02 Dec 2009 05:47:51 GMT LionelS http://groups.yahoo.com/group/Amateur_Microscopy/message/2904 http://groups.yahoo.com/group/Amateur_Microscopy/message/2904 Interesting. So the 55mm sits over the base instead of inside the base filter housing. I have a polarizing filter that Mike Shaw made for me like that. I'll Wed, 02 Dec 2009 04:27:27 GMT Chris Robinson http://groups.yahoo.com/group/Amateur_Microscopy/message/2903 http://groups.yahoo.com/group/Amateur_Microscopy/message/2903 Don't laugh about fried protists, it does happen!  Well, not fried actually but as soon as the temperature goes above what they can handle you'll see them Wed, 02 Dec 2009 04:25:08 GMT LionelS http://groups.yahoo.com/group/Amateur_Microscopy/message/2902 http://groups.yahoo.com/group/Amateur_Microscopy/message/2902 Thanks for the info on 2x. I do like mine. I do not have a mirror but a built in halogen. I hadn't thought of a 5x ocular. My lowest is a 10x. Maybe I will Wed, 02 Dec 2009 04:24:29 GMT Chris http://groups.yahoo.com/group/Amateur_Microscopy/message/2901 http://groups.yahoo.com/group/Amateur_Microscopy/message/2901 Hi Lionel, I use a 55mm 80B filter (blue) over the light source. I just dropped it on top of the field lens and it's perfect fit. It also keeps the dust off Wed, 02 Dec 2009 04:10:18 GMT david barriball http://groups.yahoo.com/group/Amateur_Microscopy/message/2900 http://groups.yahoo.com/group/Amateur_Microscopy/message/2900 Hi Alex, Could mail him, he's very helpful. Maby CombineZP can do it, many macros. David ...

Hi Bcrazy I have been interested in sectioning since I was a youngster over fifty years ago, and I want to help.

I'm not sure that it will help with your problem. I wonder if your system components are compatible.
