Very nice moon!

Someday, I'll come across one of these. I did pick up one Swift eyepiece (4mm, I think) at the RTMC swap meet this past may. So now I need a scope to put it in!

I took simple liberties with your image. Hope you don't mind:


That looks great :)

This looks pretty close to the original paint color for the swift 831

Yes spotted that earlier this week, looks like a very early model as the focus knobs are not painted.

Not sure about the mount though any idea who made it?

Your right I found another picture of a Charles Frank mount but this one seems to be missing quite a lot of bits, worm wheels, setting circles etc..

Some evidence to support the Swift to Takahashi lineage:

A later 1975 TS65 and quite a lot has changed since the original but the evidence is still there:

Now if I were a betting man...

I guess it's time to resurrect this thread.
Last night I purchased a 1964 Swift Model 831 from David, Lee, and the exceptionally nice people at the San Jose Astronomical Association. What a pleasure to be with fellow astronomy enthusiasts, and such outstanding people. Thank you, David!

The Swift that I purchased is SN 643028, so we have another Swift to add to the Registry.

I got it home and set it on top of the Unitron and Mayflower boxes (protected).

I have to admit, I was definitely pleasantly surprised to see the original tag still attached to the handle - the one that says: "Dealers Note: Do not remove this tag. It should be attached when you make delivery to the customer." This was taken very seriously!!

A view of the SN and the Note:

The OTA was wrapped in it's original plastic, as were the finder and other parts...a very good sign!

Beneath the tripod was a plastic bag with the original manual (in like new condition), and map of the heavens, and the moon map that was drawn by Dr. Shusuke Kojima, the brains and driving force behind the Swift scopes.

Another view of the inside of the case showing the mount, the finder in the upper left, and clam shell for the finder below it. If you look to the right, you see a place where something is missing - the Tripod Head!

From left to right there's the erecting prism, the eyepiece diagonal, Telescope tube adapter, 6mm, 9mm and 40mm eyepieces, and the 2X Barlow.

The lens is in very good condition - no scratches. However it needs some careful cleaning and there is a small spot of mold that needs to be removed. I'm going to wait a while before cleaning. I want to get some views in first!

Since I don't have the Tripod Head, I put the OTA on my 80mm Mayflower mount. The Mayflower didn't seem to mind, and the Swift does look mighty fine on it! I've noticed that the Mayflower has a much more substantial mount than does the Swift. However, the Swift has a far superior finder than does the Mayflower.

A view of the way the Finder mounts onto the Swift OTA - very nice design! In fact, I can also mount the Swift finder on the Mayflower OTA. It's only fair since they are sharing mounts.

Those are interesting legs! I've never seen an 831 with any other than the rounded reddish-brown ones. It's a real shame that the tripod hub is not included! Hopefully, someone has a 'basket-case' mount that they would part out.....
and also, if anyone has a box of 831 parts, I'm looking for a focuser knob set....mine came with one side broken off.....

I really like the mechanics of the eyepiece adapter tube with the 14 etched marks for correct positioning. Another fine feature is the way the Swift has the knurled knobs for securing the draw tube and diagonal, and eyepiece in position. What an excellent design!! I'm very impressed. And does this scope look new, or what?!? :)

It certainly looks right at home on that Mayflower mount!

And, if you haven't had it apart, the finder has an actual achromat objective, not the single DCX lens used in most finders!

That's all the pictures for now. Once again I'd like to thank Dave for contacting me regarding this really fine telescope. Dave is also checking to see if the prior owner still has the Tripod Head sitting around. Hopefully they can find it. If not, I would appreciate any help in locating one. As a last resort, I could build one...but not anxious to do that.

And one last thing, this Swift 831 is an anniversary present to me from my darling wife!! Am I a lucky man, or what!?!? :jump: When I get it outside, I want to take her picture next to the telescope. I'm calling it my "Susy" scope.
