There's been a fair amount of discussion on the Criterion Dynascope list I'm on lately regarding the best ways to blacken the inside tube of a newtonian. What seems to be the preferred method in this group anyway is to coat the inside of the tube with glue, then apply crushed walnut shells (avialable apparently at Petsmart) and spray paint with Krylon flat black. Many on the list discourage the use of flocked paper. What do the experts on this list think of this? Does such a procedure really make a noticeable difference over a simple coat of flat black paint on the inside of the tube sans the shells?
