I'm so happy with my full tube 12” dobsonian when i watch this video. Just lift the tube in the rockerbox and go. You need the room for transportation though 😂😆
Hy Roel. I like your telescope(s). I have seen them all on your blog. Very nice work. I consider that yours are the smallest, lightest, and also, nicest I have seen. And as a moderator on an astro forum, I have seen a lot. Myself, I made my first scope some 17 years ago. Now, I want to build new bodies for my 200f5 and 300f4 newtonians, in a truss configuration. And some of your ideas are very interesting for me. Maybe I will use some. Thanks for sharing. Clear sky.
I also made a dobson with aluminum bars of square section (painted black), and with the telescope rotating over small wheels of solid rubber, around a central axis, and putting on the eyepieces like a bell of rubber made with half a small ball rubber (to block side light and at the same time to place the eyepiece in the center and at the right distance from the eye) and it moved very well and very gently simply by pushing with my eye area over the rubber bell that is around the eyepiece , infinitely better than with a heavy dobson type sky watcher or similar. Something that was very useful was to mark on the lower platform (somewhat larger than the upper one) the 360º of Azimuth (and with a mark indicating the geographic North) and on one side of the Dobson a quadrant also of 0º to 90º with a small plumb line (as a clinometer) to measure the altitude above the horizon with which I located quickly in azimuth and elevation the astronomical object he wanted according to the computer data
@Roelarex Hi i have a question to you. I decided to make a telescope. But i have to small informations how to buid one like this. So that is basically two mirrrors and one magnifying glass?
Hello, This design is particularly well thought ! Really good job ! Do you have some 3d files of it ? (stl or other) and are you willing to share them with people ? Thanks a lot for your reply.
I am eager to know more about the design as well. I wonder if plastic would have the rigidity needed if 3d printed or if wood is the way to go. Also, what rods/beams are being used.
The total weight of the telescope is 8kg. It keeps its collimation very well (a must for such a fast mirror). I only use lightweight 1.25" eyepieces like Televue Delites to keep the total weight of the upper cage as low as possible. You wouldn't want to use heavy 2" eyepieces in a scope like this, for its purpose is to keep everything as light as possible. I have taken this fellow to almost inaccessible mountain terrains by simply packing everything in a small backpack.
Tell me how much you want for that 10“. I am from Germany. I am not kidding, will be in Philly April 22. Maybe you can build such a Dobson for me and I will buy it. Sorry for my bad english. I understand you don’t sell this commercially. But I want one, no matter the cost. I highly appreciate you and your craftsmanship. Pls answer, best regards Simon
this is not an astrograph, mainly for visual, although reflector astrographs are typically f/3.9, and used with a coma corrector, come in around f/4.4.
I would never recommend assembling a truss dobson in the sun. Even if Roelarex does have a strange low-reflecting mirror, which might be anything but glass.
With the cover on the primary there is no problem with assembling in sunlight. You can see me removing it after I assembled the scope in the video, but of course that's just for demonstration.
This is incredible. A 10in scope that could fit in carry on luggage! You should market this. Plenty of people would love to buy it.

"Hypersleep" by Jerry Goldsmith; well chosen! ...en gefeliciteerd met je ontwerp, een echt kunstwerk!
very nice! That is a beautiful design
This is so neat and beautifully made (both the film and the scope)
Looks like Alien's 1979 soundtrack IS used here.

Zo mooi!
good job , nice
no way that's awesome
wow. I want one.
Nice👍
Congratulations, it looks minimalistic and light, yet so beautiful. Any live views?
Do you build for yourself or do you also sell them?
Beautiful video, liked and subscribed! Did you observe with it also?
Супер видео, музыка класс. ❤
Its a Pierre Strock telescope ! :)
it looks very slim/small for a 10" mirror!
i think think its the focal length
@@mikebenengtouncry3613 Ha ha ha.
@@user-vx8jc8ii9p bruh stfu that was 11 months ago I was a kid ... :|
IMO, a 10" can easily be a solid tube. Not heavy at all. Unless used for a travel scope, then it is more practical to make a 10" truss.

Surprised I haven't seen this on Aliexpress yet
That's perfect am 5 ft 4 wish arthritis in y back where do I get 1
Alien movie ost?
whatever it is, its damn amazing lol
mec faut commercialisé ça vraiment tu va te faire des Boules en Or Massive !!!!
I need the plans for this please.
Can you please share the drawings/design of this little scope? So other DIY can build it.
awesome one! how much dose it weight?
The total weight of the telescope (including trusses etc.) is 8 kg.
Incredible! Which focuser did you use?
I made the focuser myself out of an old camera zoom lens: www.cloudynights.com/topic/174947-helical-focuser-from-a-camera-objective/

@@Roelarex what kind of material is used for the truss and how did it affect on the performance of the telescope?
Did you make this or purchase it? If you bought it I would love to know who makes it.
I made this one myself. More builds can be found at www.roelblog.nl

Hi.how much does this cost to you?
same music in alien -whats the name?
How much does it weigh?
It has a total weight of 8 kilos (17,6 pounds)
Nice job!
Do your truss tubes screw together or are they standard tent poles?
You can see him screw them together if you look closely there is a brass insert
Why F/4?
F/4 has lot of coma and used as an astrograph?
Good job though!
this is not an astrograph, mainly for visual, although reflector astrographs are typically f/3.9, and used with a coma corrector, come in around f/4.4.
You must constantly collect dirt on that mirror lol
Still mostly starlight though! :D

Looks like 8 inches
Star Wars
200 not 250 ?
It's a 250mm f/4
Can u build me one? I'm a truck driver I don't have room for a telescope
holy crap thats tiny lmao
