Alex, from a noobs point of view I just have to say brilliant engineering and an absolutely magnificent beauty for the eye to behold.

And all that weighing in at 21kgs.

I assume that Plug and Play with ArgoNavis means encoders are either fitted or appropriate mounting points have been integrated.
These instruments are not aimed at the "cheap'n'cheerful" end of the market. That end is well serviced. Adrian alluded to the niche market that these scopes are designed for. Portability, ease of use, finish, design, all these make for a premium, but not an astronomical one (pun intended). I've been mindful of that in the way I've structured the prices.

Other than the optics, what you see in the first lot of photos is what you get - the only things not shown in the pics that also come with the scope are the encoder couplings, and a special tool. The encoder couplings are not necessary for the function of the scope. So as far as bare-bones goes, you can get going with what you see in the photos. Should you then like to get an Argo Navis or other navigation system, the facilities are there from the start (no dicking around to make bits fit), and other accessories can follow too.

There will be other sizes. I've started with a 12" as this size is the largest really practical 'small' aperture. Smaller apertures than 12" don't work as there is just not enough glass for ballast in the OTA. The upper end would be 18" - any larger and the weight is just unsafe for one person to handle, and their portability is more limited. Larger apertures may be considered as special custom pieces, and there is already a brilliant large diameter telescope producer here in Oz that is capable of dealing with the largest of apertures. Gondwana is mainly concerned with producing more highly portable instruments.

Optics

This is an important part of the way the prices will be structured. The base price does not include optics. There are 3 different ways that optics can be sourced to accommodate different budgets and requirements.

i - Donor optics from an existing OTA

ii - Self sourced new optics - these can be from the least expensive to the premium end

iii - I can supply them. I have been looking for a line of optics that will compliment these instruments. This task has been going on for a very long time - even before Gondwana Telescopes was inspired. There are good optics available that are relatively inexpensive. But, what I will offer are better optics that will compliment these instruments. Then if you want premium optics, these can be had from the United States or Russia. The optics I will be offering will surprise many, but it is something that I have been at great pains to make sure that these are really damn good. I finally have found a source that I have no problem in putting into my own scopes, and happy to supply.

As these instruments are custom made, it will be important for me to have the optics to both create a balanced OTA, the correct length of the carbon fibre poles, and the appropriate size mount.

I can only repeat that the scope looks great and it does fill an unoccupied niche in the Australian market. Congratulations. Of course we are all interested in the $$$ but I also have a few other questions.

Is the box fully sealed and dust-proof? If I was to take one on the round Oz retirement trip it would have to survive some serious dust at times.

Can the optics be protected while the scope is set up? It would be useful to be able to protect the optics during the day without having to disassemble.

What are the box's dimensions? Space will be limited.

Must the box be stored and transported in the horizontal orientation or can it be stood up on one of the smaller sides? As I said, space will be limited.

How much weight can be stacked on top of the box?

I have to ask... are you going to have a website for prospective buyers or is it going to be by word of mouth.

I say this as someone who couldn't possibly afford such a beautiful object.

That 12" model show here by Alex. With a little practice can be assembled in 5 min and disassembled in the same time frame. Alex's design makes perfect sense in regards to packing the scope up and hiding it away under a table or a car boot during the day or when not in use. If you have a large FWD you could probably fit it under a car seat. Pretty good for a 12"er indeed. If you have a 2 seater like an MX5 you could put it in the boot easy.

It's not air tight if I remember. If you have a problem with bull dust (who doesn't?), you could put it in say a standard garbage bag and tie the top off just as you would with other things you want to keep dust free. It would fit in the bag without any trouble.

Profile wise its really compact folded up. Both my eyepiece cases have a taller profile. (Only just though, its still a 12" scope).




Wish I could retire and go for a trip around Oz. With a scope even more so.

The box dimensions are 200mm tall, 605mm wide by 415mm deep. These dimensions can change a little depending on the final size of the alt bearings.

There is a packing pattern that will allow the box to be stood up on one of the small ends.

The base model is not dust proof. I would never claim 100% dust proof. The mirror box is the easiest to make dust resistant, & closest to dust proof. The mount can have provisions added to make it a lot more dust resistant. There will be a "scope swag" available for the stowed box (SURPRISE! more on this later), and I guess if something more dust resistant is required it can be custom made. A cover for the assembled scope is also being designed (second SURPRISE!)

The mirror box has a sturdy cover. The secondary comes with a soft pouch. So it can be safely left assembled. This is not a solar scope, nor is it designed for solar observing. ALL CARE must be taken to ensure the sun does not shine directly on the primary mirror! NO open truss scope should have sun light shine directly on its primary mirror.

It look good but will the price be attractive enough vs the mass produced ones?
Can you gives an indication of the price?

Like I mentioned earlier, these scopes are not there to match the cheap and cheerful. In the end you get what you pay for. There is a difference between mass produced and hand crafted.

Its like cars - an old Beetle will get you from A to B, but don't expect a Beetle to perform like a Ferrari. Or a cheapie plossl vs a premium end eyepiece. You get what you pay for.

How much? That is for the launch date. For now this thread is to put a face to Gondwana, and to give a taste of what is to come.

Another feature that hasn't been mentioned is dew control. I don't imagine you've forgotten that issue. After all you wouldn't want you Ferrari bogged in a puddle.

Oh, BTW do they come in red?
