Grubb Standard Equatorials

[MalcolmM]

I'm currently co-authoring a paper on the Armagh 10" Grubb refractor. As part of our research we are trying to find out about other Grubb Standard Equatorials of 8" to 15". Are they still in use? Did they do scientific work?

There are a number of these still in use around the world, a testament to their longevity and craftsmanship.

Is anyone able to share any information on Grubb Standard Equatorials? Particularly around whether they are still in use and have done any scientific research?

I've posted these pictures before, but here they are again, just because it is such a lovely instrument!

Many thanks, 

Malcolm

Is that Armagh Obsy, Malcolm?

That's correct @JeremyS. They have a number of beautiful old medium sized scopes, but the Grubb refractor is the nicest by far

I don't know whether you are familiar with the Irish National Inventory of Historic Scientific Instruments which is available as a PDF from Google Books - it has a list of Grubb telescopes amongst other items

It might be useful if you've not seen it before.

No, I have not seen that before thanks. My supervisor may well have seen it, and I've been going off a list from Ian Glass's book about the Grubbs. I'll certainly check that out. Thanks again,
