Hi guys,

This is my first post here

I have this old scope that  has been neglected for many years and spent a bit of time underwater.

I am going to be renovating it shortly so I am looking for any information I can find on it or similar.

I would like to make it as true to the original condition as possible.

Any input or advice would be greatly appreciated.

It is a 8 inch F 8 ( or there abouts) .

This is a beauty. If the optics are good it will provide good views of everything, specially planets and doubles. And that mount, when properly working, must be rock solid. It is not exactly a grab and go, so perhaps you have to think of a more or less permanent place, at least for the mount. It seems it will be a lot of work to make it shine again. But a fun project, though. Good luck and keep us updated! waytogo.gif

welcome to Cloudy Nights.   That looks like a wonderful project.  You will need a lot of rust remover.   Should look fantastic when you are done.

  Looking forward to seeing what the optics look like and what the mirror is made of  since they were still making speculum optics up into the 1930's  

   Any idea what observatory that it was located in, originally ?

What a wonderful instrument!!

 

First thing I would do is get in touch with the Antique Telescope Society.  Several of their members post here, so you might hear from one of them soon.

That's a beauty now and will be even more so when you finish with it.  What's the story with it being under water?

Great looking instrument, certainly a fun project.

 

Any images of the primary mirror +  secondary ?

That will be beautiful when restored. I enjoy looking at Google images to see what images of my telescope or one like it have been posted. Try it out if you have not already.

Thanks for the welcome guys,

To answer a few questions.

Regarding the optics - The primary mirror is 210 mm ( a bit over 2 1/4 inch ), coating almost completely gone.  secondary mirror and holder are AWOL.

Finder scope is a unitron 10 x 40 - maybe salvageable but crosshairs gone, eyepieces - bin job.

It had a brief career as a periscope during flooding, twice.

It was bought to watch Hailey's comet by a private school I'm told it, then not used again then pulled out during renovations about eight years ago and destined for the scrape yard which is when I acquired it.

It weighs in at around 400 kilos or 900 pounds if you roll that way.

The research I have done so far tells me it is at least 75 years old and possibly over 100.

I posted it to Reddit a couple of days ago and they suggest posting it here, there is quite a bit of interest in seeing the renovation so I am thinking of videoing it so people can watch the progress.

Is that perchance the same John Browning of the Browning Arms Company, inventor of the Browning BAR (.308 gas-operated, semi-automatic rifle)?

 More likely the John Browning of London who is more well known for making spectroscopes https://en.wikipedia...nstrument_maker) . According to the Wiki article after 1908 the Browning company was taken over by W Watson, so the scope maybe older than originally thought since that has the John Browning name attached.

Oh that's right! The Browning pocket spectroscopes like gemologists use. I forgot about him. I have one I adapted for telescope use. It works pretty well!

If you mean bought to watch Halley's Comet in 1910, then that story is not true. The clunky RA drive is not original and has been retrofitted later (electric motors was NOT an option on amateur telescopes until well after WW1), so the scope must have been used at least a little for some time after the initial purchase.

Hi, 

For many years a Browning eight inch Newtonian replaced the Plossl refractor in the Athens Observatory. Now only the tube lies in a store room. Mount missing. Hope this thread to initiate a restoration project.

86 I believe, I don't think they bought it new.

Cheers

Are you sure that's a Browning and not a Calver?

 

I've always loved that style of GEM.
