To be fair, NASA do have access to some pretty large binoculars !

I have just been catching up with the latest news on JWST in one of my favourite publications. This report, dated 26 Jan, suggests that one can spot the observatory in the bowl of the Big Dipper with binoculars.

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.

Hi David,

The large lens (7 inch) may well be the original 7 inch  f/7 Zeiss astrograph lens that was missing from the Mond when Glyn Marsh and I rescued the instrument from NLO. The 7 inch lens was missing and was not amongst the other astrographic lenses we collected and are now back at NLO with the Cooke/Mond Astrographis mount. The 7 inch that you now have was one that Harold Ridley passed on to Glyn and did not come originally from the NLO.The lens design of the lens you ahve just found may be that of Petzval Doublet. The small 3 inch refractor looks like a guide telescope with a sliding plate that carries the eyepeice and diagaonal across the FOV to allow the observer to selected a guide star. I would guess that both instrument s were part of the original Mond Astrograph or from another of the large telescopes there at NLO. I have taken the liberty of posting your message and images on the Antique Telescope Forum to see if anyone ther can more positivley identify these instruments. Denis Buczynski

No. Image link your photo then go to Telescope->Start up->Star Synchronisation.  It’s the last option.  I have not tried this as it would disrupt my model.  You may need to have clicked on the linked photo on the sky display to make it active but again not tried it.
