But the column itself was designed to be adaptable. The top plate can be taken off altogether and there are holes left for connection.

I finally found the right tripod for my setup, an Elephant Stand made by Gerd Neumann.

I have no idea how I could miss out this stand until today, it is just perfect in size, height and stability.

The column will fit directly into the center tube.

We’re waiting for your review.

It looks very appropriate. It it seems like it can be disassembled using 2 screws.

Yes, each leg is attached with one screw so taking 2 legs off is two screws.

Maybe for short trips in the car it is possible to take just one leg off.

 

I will machine my own center part out of aluminium instead of the steel one.

This is enough for my load and will reduce the weight.

Jochen, with your metal shop and skill, you can build your own tripod (?)

Garret, such tripod legs need to be casted, that is something I can not do in my workshop.

Perhaps, if possible, I will only buy the legs and build the center part my own.

Now this tripod looks like it is up to the task of using that amazing new geared column!

 

I'd love to see if you can properly adapt them to work together.

Yes, my feeling is finally all is matching perfectly now.

The bino, the column, the fluidhead and the tripod.

Rock solid but still portable.

 

It was a long way but now I am at the finish line.

In case anybody was curious, I finally had the binoculars out at a dark site and wow do they deliver! They are everything I have hoped for, and everybody else who tried them was impressed. I know we all say this, but this might be my final binocular, unless of course APM can figure out how to make an 180mm that weighs no more than 20kg  lol.gif

 

The collimation is more demanding under the stars than during the day, but the adjustment was small and easy with the tool provided by Lunt, it's now perfect even with the 3.7mm Ethos.

 

I really like the Star Sense app too, thanks for the tip Jochen!

 

Cheers everybody!

These are great news!

Hopefully next week my setup will also be ready, the tripod modifications are still in the making...

Ethos 17, 10, 6 and 3.7. The 3.7 didn't get much use yet because I didn't have time to make counterweights and barrel extenders for them yet, but it's coming. I also tried a pair of Nikon HW 10mm, they are very good but a little more difficult to get my face in close enough, compared to the 10 Ethos.

 

Most of the time I used the 17, and the 6 when I wanted a closer look.

I am making a new center piece for my Elephant tripod with 110mm diameter out of duraluminium.

The original center piece is out of stainless steel and has only 100mm diameter but my rack and pinion column does need a 110mm flange.

 

Interesting you do not speek about the 8mm Ethos.

I am still not sure if I need the 8mm between the 10mm and 6mm

 That's because I don't have one lol.gif  To be honest, I don't miss it. It seems most objects are either too large for even the 17mm, and when I want to see something smaller, I go right for the 6mm. I promised myself that 8 eyepieces are the limit of what I want to carry around with me, and I haven't felt the need for something in between the 10 and the 6. Maybe that will change in time but I hope not.

I do also like the 13mm Ethos with their 2.3mm exit pupil

And I do have the 4,7 for days where the seeing does not allow the 3,7 but more than just the 6

On the long side I have the 32mm Kasai which are unobtainable today.

The 32mm Masuyama are close but not equal.

 

For me it is not only about magnification and exit pupil but also nicely framing the objects.

Here we go.

 

It is rock solid, not the smallest movement or shaking.

Selling?

You are kidding.

 

This setup was finished just today and I started planning it 5 years ago.

This one will never leave me.

 

But all parts are available on the market, you can build a copy.

Jochen,
I would never be so bold as to ask whether you'd sell this setup :)
I was referring to your modified tripod. I suspect there are people who would be interested in such a tripod that is appropriately modified for the geared column you have but don't have the machines or skills to do the mods you've done. Just a though.

Looks like a great kit!

Is the elephant tripod foldable?

It is not foldable but can be taken apart very quick easily.

Each leg is mounted with just one screw.

Taking just one leg of already makes the tripod quite small and well transportable
