Hi Phil,
Mark was telling me about your mirror at Lostock last weekend and it is great to
see that such a carefully figured piece of glass has found its way into such a
beautifully crafted telescope.
F/3.7 is the perfect prescription for those of us who are vertically challenged.
May many nights of enjoyable observing be your reward!
