DEAR SIR,—I have mounted the 5-inch speculum on a simple equatorial
and it works well. I am sure it will turn out a fine glass and I
shall not regret the time and pains I have spent over it. It is not
quite in adjustment yet, when it is it will afford me a treat. I
have just tried it once on the Orion Nebula and Trapezium, details
of Nebula well seen, and the 5th star in Trapezium easy.
