The plates once secured, can be laid by for future study by daylight and at leisure. The record is there, with no room for doubt or mistakes as to its fidelity.
Page 276 - It is reasonable to suppose that on some lofty mountain and in a purer atmosphere we might, with the same telescope, include the eighth magnitude. To increase the size of the telescope threefold in aperture is a practicable thing if the money can be found. This would increase the brightness of the stellar images, say eightfold, and we should be able then to photograph all the stars to the tenth and eleventh magnitude, inclusive. There is nothing then so extravagant in predicting a future application...
