What reading level is Half-Hours With the Telescope book?
To quickly assess the difficulty of the text, read a short excerpt:
] I may note here in passing that Sir John Herschel's delineation of thenorthern portion of the Milky Way, though a great improvement on theviews given in former works, seems to require revision, and especiallyas respects the very remarkable patches and streaks which characterisethe portion extending over Cepheus and Cygnus. It seems to me, also, that the evidence on which it has been urged that the stars composingthe Milky Way are (on an average) comparable in magnitude to our ownsun, or to st...ars of the leading magnitudes, is imperfect. I believe, forinstance, that the brilliant oval of milky light in Cygnus comes fromstars intimately associated with the leading stars in thatconstellation, and not far removed in space (proportionately) beyondthem. Of course, if this be the case, the stars, whose combined lightforms the patch of milky light, must be far smaller than the leadingbrilliants of Cygnus. However, this is not the place to enter onspeculations of this sort; I return therefore to the business we havemore immediately in hand.
