rowan46 Posted April 8, 2011 Share Posted April 8, 2011 If two way glass was used in a maksutov or newtonian as the central obstruction would it work to give a more contrasty or brighter image? just an idle and probably useless idea Link to comment Share on other sites More sharing options...
Peter Drew Posted April 8, 2011 Share Posted April 8, 2011 Probably not much advantage even if it did work as the perforation in a Mak or SCT primary mirror is similar to that of the secondary obstruction. . Link to comment Share on other sites More sharing options...
