Lee, post 57,
When you and the other BF particpants are finished to remove the diamont dust from their focussers (the application of this dust is a perfect method to let focussers turn very smooth in all directions, even upside down) I have another puzzle to study: a picture of cutaways of two SV 42's which differ only in age: one is produced a couple of years before the other.

Hi Gijs
Naughty!
The one on the right:
Does not have field flattener
Has no focusing lens
Has only one prism, which will not transmit light to the eyepiece in its position.
Therefore it is one of the bins that Jan said was cut open with a water-jet and it sent lenses flying in all directions!! :king:
Lee :-O
