I not sure I'm following this advise. It would not seem that a optical
window would complicate the use of the scope and would address the main
bugaboo to optimum newtonian performance - tube currents. The complexity is
in the construction is it not? If that is the case why not build the scope
and put it in use without the optical window and then go to work on the
later. It would seem little would be involved in retrofitting once and if
the project is completed. Personally Texaru's discription of the benefits
has long made me wonder why more have not been made.
