From Rev. S. Mills, M.A.
Droylsden,
September 4th, 1880.
Dear Mr. Calver,—To-night was an exceptional fine night for the stars, the like of which I have not had since I got your 6-1/2 in. I had for a week or so been observing with my home-made 8 in., but to-night again recurred to yours, and its superiority was all the more conspicuous and gratifying. It quite delighted me afresh!
Looking at β Cygni, I picked up two, to me, new stars, which I think fully completes Mr. Sadler’s tests in this field. I mark the newly found ones in red. This only shows that one has only patiently to watch and wait for a suitable observing night to get one out of a certain aperture it is capable of showing.
The vast superiority of your 6-1/2 in. has quite put my 8 inch out of court!!
Yours faithfully,
(Signed.)
Mr. G. Calver.
