Re: home nade 4 inch scope based on davidG hand held scope
thx
it worked better than i thought
there is no barlow - that is prime focus
4 inch f/12 is a bit too long
im going to try a 4 inch with faster f ratio
so simply you can convert an external etalon
to internal etalon by just adding lens to make light parallel
why is this not done more often?
