"Historic With-Browning Telescope with Unique Provenance"

Interesting article by Robert A. Garfinkle, F.R.A.S. in SJAA Ephemeris for May 2001

Happy self-isolation :roll:

Thanks for the fascinating narrative (and an interesting glimpse back to the year 2001).

We should thank our lucky stars that we have mass-produced instruments priced at only a quantum leap above toys that achieve and surpass the standards of the steam age.

That being as it may, the fact remains that the device is simply lovely to behold.
Up until about the middle of the nineteenth century, engineering drawing was learned in the long tradition of architectural drawing, and many early machines, such as large steam engines, were designed with iron structural elements cast in the forms of columns of the classical orders. Functional brackets were adorned with the classical motifs that students had learned in drawing classes, which consisted largely of copying increasingly complex architectural drawings, and one can only speculate on how much of what came to be known as Victorian architecture and structure was influenced by this practice. -- From The Pencil: A History of Design and Circumstance by Henry Petroski, Alfred A. Knoff, 1990, (page 223).

Very interesting. How fabulous to own such a telescope with a history stretching back to 1874.

Quite a few interesting articles. I bet Jay Freeman’s log books are worth a look through.

I like Dave North’s sub heading of “Don’t waste that twilight: look at bright things and check for seeing”.

Hope your self-isolation doesn’t last too long.

Best wishes, Jeff.

Interesting article Mike. It's nice to know that it went to a person who appreciated the history of the telescope. The old 12 inch Calver that I borrowed from the BAA many years ago went to a Victorian-style observatory (The Wrottesly-Phillips Observatory) after I passed it on. It had originally belonged to TER Phillips, the noted Jupiter observer, and I believe that he later put an 18 inch reflector (formerly owned by NE Green) on the mounting! I remember having to do a complete restoration job, including replacing all the half-inch ball bearings in the bearing track of the RA assembly. These old telescopes are dangerously heavy, but the mountings are the most stable you will ever come across. Kind thoughts, Bob

See, also, The Great Melbourne Telescope. "The Great Melbourne Telescope was the largest fully steerable telescope of the 19th century."

it is humbling to understand what was achieved.

This is the 12-inch Calver nearing the end of restoration

Good grief, that's a beast. Did you ever get to observe through this telescope, Bob?

Best wishes, Jeff.

Yes Jeff, as you can see, it squatted in my back garden on the base of a former observing hut that I made for an earlier telescope, an 8.5 inch AE newtonian. I covered it with the tarp that you can see in the background. I used it mainly for Jupiter and Saturn. I made a set of observing steps to observe from, and there are two handles on the tube that rotated in its cradles so that the eyepiece was always conveniently placed. Kind thoughts, Bob
