Denis, we have a meeting on Friday to discuss and plan the re-instatement of the Mond telescope. We shall do a comparison of lenses then. We have been busy with a general refurbishment of the NLO entrance foyer, and the Mond is the next item on our to do list. I’ve just found this Jim Lockyer lantern slide of the Mond as new, taken at the Cooke works circa 1931. Interesting that Robert Mond paid £2171-5-9 for it which is £161,457 in today’s money.
