LIST OF OBJECTS SEEN WITH A 5-1/4 INCH REFLECTOR.
ξ Scorpii (5, 5·2 : 1″·3) clearly divided, 186 power.
ε Lyræ. Debilissima quite easy; 186, 380 powers, though nearly half Moon.
μ^1 Herculis (9·4, 10 : 1″·04). Just divided, 380. Very difficult, owing to its faintness.
Vega. 11 mag., comes quite plain, only 47 minutes before sunrise; powers 110, 186.
φ Virginis (5, 13 : 4″·27). Comes plain, 110, 186.
ν Scorpii, the close pair (4, 5 : 0″·8), well elongated, power 380; small star (7, 8 : 1″·68) divided, 110.
ζ Boötis (4, 5 : 0″·88) elongated 186, notched 380, and with field lens removed, all but divided.
δ Cygni (3, 9 : 1″·63), 9 plain, 380 on several occasions.
Antares is chiefly an atmospheric test, but the companion was quite plain on one occasion out of the three I looked for it.
μ^2 Boötis (7·5, 8 : 0″·63), considerably elongated, 380.
η Coronæ (5·5, 6 : 0″·62), slightly elongated, 380; but not nearly so much as μ^2 Boötis.
56 Herculis (6·5, 13 : 15″), 13 easy, all powers.
π Aquilæ (6, 7 : 1″·5). Just separated, 110; 14 mag. (Webb), just visible, 186.
ε Equulei. Just divided, 186 (5·7, 6·2 : 1″·0).
MY DEAR SIR,—I have at present to use the telescope, an 8-1/2 in. Alt Azimuth, out of a window, and so at a great disadvantage,—in fact cannot give it a fair trial till I have the house ready for it, meanwhile I use it as occasions offer, and have been highly pleased with it. The views of the nebular in Orion resemble those of BOND’S drawings, and shows immeasurably above my 3-1/4, of course. I think the mirror is _perfect_ from its performance on large stars whose disks are small and round, without rays of any kind. I am _thoroughly_ satisfied.
DEAR SIR,—I have not been able to do much with the telescope, a 5-1/4″ Angle-block, through the unfavourable weather for the last four months, but with the opportunities I have had its performance is satisfactory; it performs well on stars with high powers, and I am sure it will bear a good deal higher. I am very well pleased with the instrument.
_From_ THE REV. THOS. H. BROWNE, F.R.M.S., &c.
THE CEDARS, HIGH WYCOMBE, _February 26th, 1880_.
DEAR SIR,—I am exceedingly pleased with the action of your mirror (an 8-1/2 in. equatorial); what I have seen of sun, moon, planets, and stars is splendid. I have had a good many telescopes, but never liked one so well as the one you have sent me. For the first day or two I could do nothing but admire it.
