While waiting for my new Vixen GPD2 to arrive from Japan I decided I needed an astronomy restoration project to keep me busy. Here she is:

This is my 'Gaunt Equatorial Telescope Stand' made by Thomas Gaunt, Optician and Jeweller, Melbourne circa 1885. She is certainly no lightweight:
The triangular pier stands 41" tall and weighs in at 137lbs
The iron and brass equatorial mount is a relative lightweight at 82lbs
The single counterweight is a featherlight 35lb

I will be restoring the mount to its former glory over the next few months and once complete she will scan the heavens from Jindabyne, Australia.

Being a bit of a brute of a mount, she needed something equally hefty to carry, luckily I was able to buy a mint condition Istar Perseus AT150 F10 and although they had an age difference of 125 years, it was a match made in heaven. :bow: :bow: :bow:

Thank you for the replies, yes we are lucky to have found this piece of paradise with view that can never be built out.
I have now dismantled the mount and have am doing a DIY thread for those interested in the 'Old Girl'
So the Refractor has gone back into hiding for a little while. :( :( :(

Here is a pic of a morning storms that passed by a while back.

It's hardly "little", but a beauty nonetheless. The Istars are unique and most compelling.

Beautiful mount and scope!

But I wonder if the GPD2 is able to handle the weight and especially the lever of the Istar.... looking forward to your results.

best regards
Chris

Thanks guys, I love the combination!
Hi Chris, the GPD2 is not for this scope, it will carry my Vixen R200SS F4 Reflector for AP. I bought this mount with a view to building a large refractor one day. Then by chance the Istar Perseus in mint condition became available at a great price so I bought it for the Gaunt Mount.

Ah OK I am relieved to hear that... anything else would have been a surprise. ;)

I would love to hear how your Istar performs.

best regards

The refractor is having a little rest in its case while I recommission the mount, after 2 days of intensive disassembly and polishing things are starting to look promising: Gone from this:

To this: 37 lbs of brass and bronze hidden under a gazillion coats of various black paints gathered over 135 years!

Wow you uncovered a real GEM under the layers of paint!

Do you plan to paint it or give it just a clear coat?
Would be a shame to hide the metal again.

I'll be following your other thread. Looks awesome. And what a great view you have, even when it is cloudy you still have something great to look at.

I hope you're going to wear a lab coat when you look through that. And maybe tease up your hair a bit. :)

PS - it's gorgeous.

Having now had some time behind the eyepiece of this combination ..........
I am thrilled to bits to say the least.

The 135 year old mounts axles move so very smoothly, in fact, so smooth is the action that a 1/4" movement of the focuser has the tube moving on its own. I have just begun gathering the required bits and pieces to install slow motion controls to the mount.

The Istar Perseus At150 F10 coupled to a 2" diagonal and Vixen's lanthanum eyepieces gives superb views, I have also installed a Baader Semi Apo filter, although this is actually not necessary on anything but the very brightest views.

A sliding tube weight system with brass weights is in the works as is a new finderscope using some vintage mounting rings.

The counterweights for the current setup are powdercoated weight plates.
