You remove nuts from fixed threads and the poles lift off. The bolt thread is a fixed part of the mirror box.

The poles just have holes in to push onto the threads. Each side and pole is numbered so it’s easy to get them on the correct side.

You can see the attachments and the fixed bolts in one of the pictures in this post

Thanks Alan.

I should manage to contact Dave on Saturday to see whether my requests are not too demanding for him.

Early April I'm going to Italy for a few days and bring the Moonlite CR2 and glatter collimator back to the UK.

I spent nearly 6 hours with my 14" DL dob at my dark site on Friday night. It blew my mind. I've owned 12" dobs in the past, not a lot of difference between 12 & 14 but the optics in my DL simply destroyed all previous experiences. I'm very interested in your specification requirements. David is a great bloke, you won't be disappointed.

Thanks Alli. What are the specs of yours if you don't mind?

 

Update: David replied that the requested specs should be fine. I'll post more about this when the project is confirmed.

Congrats, Looks like a very nice scope. the weight of it is even significantly less then my 10 inch Skywatcher Flextube ?.  Even got the curved spider vanes design, nice thought, and a friendly F ratio.  My only deterrent  would be the assembly time if you have to do that each time,  taking it out of the house, or fitting it in car.   The main reason  l love the flextube design is for travel in a small car , yet it is very quick to setup each time. The tube is build like a tank too which make it quite heavy, but you'll not dent it  .... unlike the much more expensive Orion UK Dobs I saw last year at a party. ?

I asked David not to paint it as I prefer the wood colour on dobsons.

Other things I asked are: black RACI finder 9x50, telrad, glatter sling, hand knobs instead of wingnuts for attaching the poles, my Moonlite CR2 focuser to be installed on the right (instead of left) side of the telescope, 4-vane spider for the secondary, wheelbarrow handles to take it around without disassembling the telescope, light shroud, black satin anodised truss poles. Finally, I asked him to balance the telescope for heavy eyepieces.

It was nice to discuss these features with him. Really nice gentleman.

My docter will give 2mm exit pupil and almost 150x with that telescope. 

Looking forward to it. :)

I went up by an aperture diameter factor of 1.5x too, and was "wowed" ;)

I bet you were/are! You've got a great scope! 

I thought about getting a 14" f5, but the 12" f6 is a better match for me and my eyepieces. Coma is also minimal, so no need to add a coma corrector in the future. Testing the impact of a TV powermate on my docter, made me realise that I didn't want that extra TV layer between the mirror and my eyepieces. Different story if one predominantly uses TV eyepieces of course.

You've put a lot of thought into your decision :thumbsup:

I used my 10" eyepieces for the first year with my 15" f/4.43: Pan24, N13T6, N7T6, PM2.5x - with no Paracorr. It was fine, but I then tried a 20mm 100deg EP and really liked it.  I had been thinking of a N9T6... but took a punt on a 10E - my 2mm exit pupil EP!  Unfortunately, I really, really liked it... And fell down a slippery Ethos slope which included the Paracorr2 over the next year or two.  But with the P2 it did require re-balancing the scope with a fixed counterweight for minimum fuss.

I'm done now though - no more EP purchases... ;)

100 deg AFOV fever! :)

More seriously, I think you made a good investment. At that focal ratio, I would also have purchased a coma corrector.

For some reason it seems I don't get the 100 deg bug... although I enjoy my 20mm Lunt, I wouldn't mind if it had an AFOV of 70-80 deg.

I keep trying to catch the 70 degree bug so that I can get rid of my Ethos's and stick to my lovely 1.26" eyepiece set. The trouble is, when the 12 inch dob is out and I compare the views, the 100's steal the show every time :rolleyes2:

I will report back on this after I will have tried my 2" set on this new 12" dobson. 

So far, what I wrote holds for my Tak and 8" dob. Not sure but I think it has to do with the shape eye-face. For instance, the docter and APM UFF have just perfect ergonomics for me...

      Very happy with it! Wish the sky were clear, but as we all know, when we buy astro equipment, it's cloudy! Argh!
      The telescope was collected from David Lukehurst at noon and then we travelled back to Cambridge. 
      John Nichol primary mirror: 37mm thickness, Suprax. Hilux coated. Optics 1/8 PV wavefront  1/27 wave RMS. Strehl .95. Secondary mirror: 62mm MA.
      Here a few photos:

      Could someone post a photo of the altitude bearing, please?
      I would like to know how this is attached to the tube, its thickness, and whether it is removable. 
      Thanks a lot!

      I wouldn't want to miss observing the Sun in a full-size 300mm filter, the detail compared to smaller instruments is such a joy to see. I do have an off-axis mask for my 300mm dob but not all the time. If daytime seeing is too bad for such a large scope, I'll switch to a smaller one, but the extra resolution and ease of spotting micro-detail thanks to the brightness is something I can't do without.
       

      A sheet of 500mm wide Baader fillm allowed me to craft this. I had enough left to cut several smaller filters.
       

      To protect it I made a storage box from cardboard of obvious origin. The box had to be custom-made to save space in my dwelling, and it also hosts a bahtinov mask for nighttime. At f/5 fine focus is not too hard with the smooth single-speed focuser, but in order to enjoy moments of clarity immediately at high power, I pre-focus with the bahtinov, which sees through turbulence, what a nice invention, and simply wait for calmer air. No need to rush to fine focus and waste precious moments. This mask needs to be copied in some sort of plastic, the cardboard trial proved the number and width of the slits are fine.
       

      The rear of the filter shows the four clips mating the four button screw heads outside the tube.
       

      And this lateral view shows the sandwiching. A rigid backing plus two layers of lightweight neoprene foam cut from a cheap mat in tiger-stripe deco, its poor taste matching its 7€ price. The bottom sheet used to be a shower booth panel, my neighbor had in its garage. Hey, do you need that? No? Okay, thanks!
       

      The Baader film is held between the neoprene sheets by staples and many strips of tape. The neoprene is held to the shower booth sheet by little collars, and its edges are sewn together for a finished look. Oversize 10mm stitches didn't take too long to do, and the foam layers can be separated for replacing the film, something glue would prevent. Holes in the neoprene allow to check that the clips' bolts are always tight.
       

      Close-up of a clip. They are made of a material whose name I forgot, I only remember it is made in the UK (thanks, guys!). This is a PVC foam that's much easier to cut, drill and sand than full-density PVC, and it's much lighter (thanks, air bubbles!), which is essential for an item that's at the front of a scope where leverage is maximal.
       

      My GSO dob has four of these screw heads, one for each spider vane. They proved very convenient for attaching the filter. The black knob is an add-on to move the scope without having to grab the large tube with both hands.
       

      Pretty obvious what we're seeing here. Note the clip is flush with the tube, and pressed hard against the scope's metal rim for a very secure and tight fit. Only four clips but eight attachment points, really. Building this with tight tolerances was more lengthy but more reassuring.
       

      It is impossible to disengage a clip by accident because tolerances are too narrow, and the shower booth plastic tough spring action doesn't allow it. But should it happen three clips would hold the filter safely. All three layers of frame material are flexible, so, to remove the filter from the tube you just bend it at a corner while you lift the clip, and the clip disengages.
       

      I already rebalanced the dob by pulling the 7-kilo mirror to the rear thanks to shorter and tougher cell springs but I'm working on a sliding counterweight made of pliable steel ribbon. Adhesive felt pads protect the paint. Thanks to the large hole the 300mm filter is not too heavy (and it's used without the finder) but the off-axis mask has only a 115mm hole, so it's heavier and may require this. While I study the combinations of heavy or lightweight eyepieces, finder/no finder, mask, filter, I can change the experimental counterweight by cutting off or adding pieces of steel ribbon. Little mounting nuts and bolts through the many holes, there's always one at the right place.
       

      Ever hated to feel the Sun while loving to watch it? If you have no sunshield you did. Heat is a discomfort on the head, and light kills off contrast. So I cut a plastic folder in this weird pattern to allow sliding it between the shower booth plastic and the neoprene mat.
       

      When it's stuck there it makes quite a large area of shadow, that's such a relief. But that's also only a prototype that wants to be made again with a better material. Has to be opaque, quite thin, very lightweight, but rigid enough. I'll stumble upon the right material sooner or later.

      Hi Guys,
      I wondered if it's possible to attach a mirrorless camera (that is a camera that is not able to remove it's lens) to a telescope. Is there an attachment or a camera holder?

      Thank you, in advance

      Dear all,
      Recently I purchased one of these dobsons from ES following the good critics I read in several forums.
      The Gen II includes some improved features with respect to Gen I, 2 Nylon pad brakes, Virgin Nylon alt and azimuth support bearings (instead of plastic), counterweight bar included with a couple of 1kg counterweights, a classical ES dovetail for the finder.
      Some of these improvements were demanded by Gen I users, and are highly appreciated, but there is still some minor improvements that the final user has to apply. I will describe them lately.
      The set up is very fast, less than 15 minutes, though the assembly of the upper cage needs some patience the first times is done.  Regarding the optics, It is superb, though in my opinion the 75mm minor axis secondary is too big (other similar modes in that range use a 63mm one), it provides full illuminated views on my ES 100 degree eyepieces, the stars in the background seen in clusters like the NGC457 are astonishing.
      The main mirror cell support is a mix of support concepts, a nine point mirror cell support with a couple of rubber wheels at 90 degrees, and 3 glued slings to the mirror laterals screwed to the back of the mirror cell support, provide lateral support for the mirror. The collimation as in Gen I is done from above in less than 5 minutes.
      In the first light in semirural skies the views confirmed the good optics, as I said specially in star clusters the amount of stars which could be seen in the background increased with respect to my 200PDS, the globular clusters were literally smashed, and small planetary nebulae like M76 showed internal details.
      Coming back to the cons, as in any Chinese made product there are quality problems not solved in this Gen II, the paint coatings from the secondary cage just jumped when I changed the position of the truss brackets.
      When I tried to open the main mirror box for the first time, the scratched the yellow paint from the altitude bearings, a tolerances problem which I solved adding 2mm nylon washers between the altitude bearings and the mirror box.
      More improvements to make on your own are to make a plywood cover to prevent moisture on the main mirror while waiting for the night, to put foam pipe covers around all the tubes, they make the winter usage of the scope more comfortable and at the same time help with the vibrations damping (which even with a heavy ES 20mm 100d EP where almost insignificant).
      One more thing to add is a PWM motor controller, the fan only work at full speed, and there are so many nights when the temperature gradient does not fall fast and the fan speed can be left at a lower regime to save batteries.
      In brief, the ES12'' Gen II, it is the Dobson truss scope with the lowest price in that aperture range, the optics is damn good, the mechanical improvement done in the GEN II, improve a lot the vibrations, and the movements of the scope, though a better control on the tolerances and the paint process should be done.
      I attach some pictures taken at home and while the first light.
      Cheers.
      Mario.
