Now that Rob Teeter is temporarily (I hope) stepping back from manufacturing telescopes, is anyone else manufacturing anything like his Journey scope?  I love the idea of everything packing down into just one or two cases (plus the trusses, of course), and I simply don't have the skills to manufacture anything similar.

 

Thanks.

I am trying to think about other makers here in US but nothing comes to mind. Most of telescope builders here make telescopes like weight does not exist. In Europe however you can get Sumerian Optics, or 16" Doc Telescope dobsonian looks small enough to be packable. There is also Polish telescope maker Taurus Telescopes (16" - 70lbs, 20" - 97lbs) that makes very light units and Hubble Optics from Hong Kong There are probably some other builders but best bet you got to roll your sleeves and start your ATM project. If you not experienced ATM-er community will help.

I'll have to plug the manufacturer of my 10" travelscope (I had one of the first prototypes):

https://www.sumerian...cs.com/products

Top-notch, and they're distributed by Teleskop Service (aka www.teleskop-express.de), though IIRC they only carry the models up to 12".

 

Not sure he makes 16"-ers for the non-Benelux market. He did make a lot of 16" Alkaids and Canopus for the forum members in the past and they're all very satisfied, but whether he has time to make them also depends on how busy Teleskop Service keeps him.

 

Alkaid works quite well and it's EXTREMELY compact -- a box plus trusses. Here's a 16" Alkaid:

 

https://www.astrofor...70501&type=full

 

and this is the box it came in:

https://www.astrofor...65&d=1562263552

 

It's impressive to see someone go up a hill to an observing platform in just two hops, one with the scope and the other with the trusses and the eyepiece case...

 

If you have slightly more room, Canopus is slightly more rigid, with better collimation stability, vibration dampening and Az bearing smoothness. But unlike an Alkaid you can't just stick it in one corner of your car's boot ('trunk') and still carry all your 'normal' stuff. This thing makes its presence clear.

 

Here's the Dutch forum admin's 18"er (with beer bottle for scale):

why

 

i have two 16 f4.5's which i haven't fixed the mirrors yet... wouldn't take much to build the structure and send it on its way... send the mirror to steve dodds... both are around 1/2~ under

 

also a 13.1 f4.5 mirror laying around.

I think you misunderstood what I said. Building is not a problem if he is willing to do it. Some people do not have tools, room, skills or desire. You on the other hand are an experienced ATMer.

He is just watching his kids during Covid-19. He'll be back to work soon.

And people said Covid-19 would kill all the demand. Apparently not all the demand.

Covid is just getting started. It’s far from over, and we haven’t begun to feel the full economic effects yet.

I had a Sumerian Optics scope and it was excellent. Highly recommended!

Thanks for the suggestions. I'm nowhere near being able to afford a scope just yet, but I really like the idea of being able to store the scope in a couple of boxes which I can easily put in the back seat of my car for observing at a distant location.

fake news.... thought it was currently funny

 

its no problem to throw a scope together for any mirror you'd like... make it very portable... having a seperate "box" for the mirror storage isn't a bad idea also.

There is also Dobson Factory  with their amazing Travel kit 300 to assemble yourself (total weight with optics 37lb!!!)

 

Also, found few more telescopes on Telescope service website:
TS-Optics 12 "f / 5 Dobsonian Telescope

Geoptik Nadirus 12" f/5 truss, which you can buy without optics

Geoptik Nadirus 16" f/4.5 truss, which you can also buy without optics

 

Thomas if you are fairly good with tools and have room to work with look what you can build yourself:

Roel Weijenberg 8" inch travel scope,  12" travel scope,    14" travel scope

Adam Long 10" travel hexapod

Making of 250 Strock Dobson

14" Grab and Go

Uwe Glahn 14.5 "f / 3.8 Dobson

Just to mention few, there are many others.

I've been looking into this also, have to throw the ES II 10" in the mix.

If he can afford the 12", it weighs close to as much as the 10". The 10" has counterweights.

The 10" is significantly smaller and more than $500 less and the counterweights can be removed.

I've got the ES12" and I bought it for its portability as a grab and go scope since my primary instrument, an astrosystems 16" dob, is significantly larger and heavier. I intend to use the 12" more in colder weather in remote observing sites because it's easier to throw it into the back of my SUV when my hands are frozen. Today, for instance, I transported it in the back of my Subaru Forester by  simply picking up the structure from the rocker box and laying it down and picking up the box and placing it alongside it. After a 2.5 hour drive, I dropped it off at Dobstuff and Dennis is going to do some mods on it such as adding a pivot bolt, tangent arm and encoders. Dennis has a beautiful 10" F4 table top dob that he uses as his personal scope and he showed me a Vixen replica of Newton's 2" telescope that was quite a treat to see. It's a working replica with a fixed eyepiece and you focus the scope by turning a rod on the bottom of the tube that moves the primary back and forth in the tube! Both of us marveled on how Newton thought up something like this and then created it. Anyhow, I'll pick up my scope in a few weeks when the mods are completed.

SImple - a tax bill!
