Ross Stalking Telescope Write Up

Thank you @caberslash for this excellent writeup, and for all those who commented. I read the whole thread with interest while working on my own telescope.

I added lens specifications and a geometrical optics model. It might be useful to restorers or tinkerers. The drawing is to scale. I'm grateful for any feedback and contributions.

Optics data: Ross London Deer Stalker #3

If that's a Ross telescope, I'm Judy Garland...
 
Dear all,

I just wanted to update you on my Ross scope which I introduced to the group last year.

Having contacted Lord Gisborough's family who had no real interest in the item I found an estate inscribed on the scope who were happy to take it off my hands.

They are very keen to do more research and hopefully they can learn more of its history.

Great thread! Out of interest what would the absolute rolls Royce of sporting telescopes been? Was there one particular model that stood above the rest in terms of cost and quality?

Dollond did a lot of research and development of eyepieces and had an early zoom lens I think. They also made highly-corrected telescopes for military use. A useful set of data is in this paper, from which you can draw some conclusions: link
 
Late to the party...but I have this day just taken ownership of a Ross scope.

Just for ***** and giggles I put it on the scales...

In its' beautiful case, it comes in at 5 lbs or 2.25 Kg in new money.

Just something to bear in mind when getting 'fit ready', for your next adventure on the Hill...🥵

All their stalking/3 draw telescopes that I have handled lack the sharp focus and light transmission that we have come to expect from modern optics, their mainstay was microscopes not telescopes.

Only comparable make to Ross was Negretti and Zambra, the only other company of that time besides Ross to hold a Royal Warrant for optics. Very uncommon to find one of their stalking scopes, but was lucky enough to own a 'Mcleod' (way too big to be practical) and one of their aluminum models which was much more sensible.

Ross Aluminum stalking 3 draw, biggest objective lens version with case (option 6) was £20 in 1880-1890...

Happens that such a model is the last one that I have in my posession and will keep for the foreseeable.

20 quid in 1880 about 1300 in 2017 according to the national archives converter!
 
Are greys with a low serial number worth more in the second hand market.🤔

Depends, lenses are not coated on the early ones so you could clean them on the inside if need be. Latter ones you risk 'damaging the coatings' according to the shop.

You'll never beat the value of this one though...
 
Worked for an Italian chap who had numbers 1&2, gifted to him by Milne who used to stalk on his estate, long time ago now though, two glasses taken to the hill on a wet day, cause as you know when they’re damp and wet they’re nay much use.😂

Packed properly it's night and day difference, literally air tight so there are vent holes around the objective lens.
 
Just an update to add from me to this fascinating subject. I recently conducted a little test comparing the optical qualities of my scopes (two Ross and a Gray) on a clear bright day at around midday at a distance of approximately 1 mile viewing individual subjects (sheep and drystone walls) on the fells visible from my kitchen door.

First Ross a very early “A Ross” (possibly 1860’s) brass bodied.
Second Ross approximately 1930’s Aluminium bodied.
Finally the Grey serial number 3323 with coated lenses.

l was quite surprised by the results, the two Ross were very compatible, great clarity and sharpness of subjects but the Gray‘s similarly sharp and clear only just came out on top probably because of the coated lenses, comparing the three in my simple test proved the quality of the Ross against the quality of the Gray, all three superb examples of quality.

Top in the photo the Gray.
Middle the A Ross.
Bottom the aluminium Ross.

Sorry about the quality of the photo.
