My Dear Sir,—I wrote you last evening, and afterwards had my first trial with the telescope (a 10 in. Alt Azimuth). It turns out a beauty. I had the full aperture on all the evening, the air was very good, but not perfect. Alpha Lyræ was a splendid object with all powers, a most brilliant disk with just indications of circular rings—no wings or rays. I turned it on B Cygni, and the beauty of the mirror stood revealed, both stars perfect disks, with just the indication of perfect circular defraction rings, and the colours were most beautiful,—nothing could possibly appear finer. I consider the mirror perfect, and the stand most convenient and smooth and pleasant in action.
I am, dear Sir,
Yours truly,
(Signed.)
Mr. G. Calver.
