I have both binocular and monocular scopes and find that the Wed, 10 Feb 2010 05:11:54 GMT rodnebri http://groups.yahoo.com/group/Amateur_Microscopy/message/3696 http://groups.yahoo.com/group/Amateur_Microscopy/message/3696 I`ll just have to live with that adjustment for astigmatism whatever that adjustment was for the eye glass lens. I generally take them off anyway then the Wed, 10 Feb 2010 04:08:09 GMT Gary Brown http://groups.yahoo.com/group/Amateur_Microscopy/message/3695 http://groups.yahoo.com/group/Amateur_Microscopy/message/3695 Hi Rodney, It's the quality of the objective lens that provides the resolution.

Hi Mo, There are two good over-views of simple sectioning techniques in Dieter Krauter's "Experimenting With the Microscope" and Georg Stehli's "The Tue, 09 Feb 2010 17:26:27 GMT John http://groups.yahoo.com/group/Amateur_Microscopy/message/3692 http://groups.yahoo.com/group/Amateur_Microscopy/message/3692 I have been wondering which general purpose alcohol recently. While I can't get pure ethanol in the UK I can get Industrial meths/Denatured Alcohol which is a Tue, 09 Feb 2010 13:37:04 GMT Tammy Moore http://groups.yahoo.com/group/Amateur_Microscopy/message/3691 http://groups.yahoo.com/group/Amateur_Microscopy/message/3691 Chris wrote: “Am I right in thinking that focusing is achieved by screwing the objective in and out?
