Thanks. :) I would really like to do it, but it's not my possesion and it's not best place, houses and trees around limit my view. I would consider a static caravan... :)
Cool! For all the nay-sayers: when you need to tweak, upgrade, or just fix something, vs. someone who bought a commercial mount, who do you think can do the work faster?! Also since no DIY is EVER done, next upgrade can be to improve the weight to carrying ratio (same strength and features but lower weight :-)). You will never cease to have something to engage your talents! To clear skies when you need them!
What a great build & a big finger up to all those who said it wouldn't work to, ONSTEP has been a game changer for me as it's got my dead CGE pro mount up & running again which I' m soon going to fit a 10" Newtonian & 102mm refractor side by side in the observatory.
great engineering with an awesome result great to see you're constantly upgrading your rig totally love the pictures currently my rig is in storage cus its winter here and way to wet to use mine currently working on my mayka mini robotic observation platform to bridge the winter wet times but will resume work when its better weather . hopeing to see more of you're work soon.keep doing what you're doing cus we love it
Thanks. :) I'm not sure, what would be the next project. I'd like to rest a bit, learn the best techniques and tricks, and enjoy the astrophotpgraphy. The Opus Magnum mount needs two minor imporovement. My main goal is the fl around 1600-2000mm, so the guiding must be improved. But I'm sure that we meet again... ;)
All that work! Well done. One of the very few! The wire on a large drum for main RA axis is my solution. Old photocopiers have the special SS woven thin cable. It has been used on a few scopes. It can be googled for a few results. The drum is not precision and PHD produces perfect stars. I recycled steel section and bearings. Which is making sense for diy and no money. You bought a lot of expensive aluminium and worm gears. It is an understanding of how the smooth motion is achieved.
Très intéressant et impressionnant. Je mesure le travail ayant construit moi même une monture à fourche. Je vais peut être vous prendre quelques idées :)
@@astrovroobel 0.5" is not good enough?? You, sir, have high standards ;) But I do understand the tireless chase towards better guiding. Let the pictures judge!
Dzięki :) Update: pod kontrolą ASIAir Plus całość sprawdza się nieporównywalnie lepiej, niż w przypadku INDI. Szkoda, ale z faktami nie można dyskutować. :)
Thanks. 😘 There is Canon EOS 6D attached, modified for the astrophotography by removing internal filter in front of the sensor that limits red ligt. It's still not a dedicated astro camera with cooling system upn to -40*C below the ambient temperature. The astro cameras do much better work, but the EOS 6D is very popular in this matter. 😊
I would love to convert a fork to harmonic drive. It has a 2" polar axle and I have looked for a harmonic gear and all I find are small axle sizes. Been thinking I could have someone make an adapter to fit the end of the axle so the smaller diameter harmonic gear would fit on it. I've even toyed with the notion of buying a current harmonic mount like the Pegasus and taking it apart and using the gears and electronics on the mount. Your thoughts?
Thank you for very informative and inspiring video! And Special thanks for the information about the subsequent improvements! Could you tell us what problems there were with the NEMA23 motor? Your impressions of the 20:1 planetary gearbox, is there any backlash, what is the speed of aiming at objects in practice - is it too slow? Thanks!
Thanks. I think I have to still work on it to get tracking like the better commercial mounts. 0.7 arcsec guiding in the UK seeing is not bad for the ATM.

Hi, Thanks. :) The ratios at RA and Ded are respectively: (360 deg * 60 min * 60 sec)/(200 steps * 32 micro steps * 20:1 planetary gearing * 100:1 harmonic gearing) = 1296000 / 12800000 = 0.10125 arcsec and 1296000 / (200 * 32 * 20 * 80:1 worm gearing) = 0.1265625 arcsec. This is about theory, while the OnStep authors say that without encoders we should roughly double the values. Anyway, using the ASIair Plus I was able to reach a total RMS ~= 0.6", but mostly it is between 0.8" and 1.2". Not bad for the home-made mount, isn't it? ;)
Nie, nadal jest, ale narazie w odstawce. Trzeba go wzmocnić, może przez wymianę tuby na carbon, albo co najmniej przez owinięcie okolicy focusera. A refraktor to Altair 102/715 EDT Triplet APO.
I mean, all you would've had to do is mute the video and play your own or watch in silence...not that difficult, yet you abandon the video, halfway through, instead?

This is the coolest DIY project on RUclips.
Cracking job. You're right to be proud. Now you're going to want to build an observatory around it.

Congratulations Vroobel! It's really impressive to see how many different domains you touch (electronic, welding, metal working...etc). Bravo!
Well, I should have a fantastic job and be rich, but non of them is the fact. Can you imagin that I also worked as coder and IT Pro? :D
inspirational build! amazing mate, absolutely incredilbe job!

Amazing work and effort. Shows what can be done with an ordinary Dob if you have the skills and determination
To say "Wow", would be an understatement. So I guess I'll just say Outstanding!
You missed one big pro of your mount: no meridian flip
Astounding and a great inspiration for others no matter the field!❤
Amazing, well done
Far from pointless. I'm considering doing some kind of similar equatorial fork/horseshoe mount conversion for my 12" Dob.
Fantastic

Could you please clarify your message?
16:55 dude how is this not a meme 💀 I guess the astrophotography community isn't big enough to have a meme culture
Very nice!
I am impressed!
This is a way!
Well Done !!!!!
Très intéressant et impressionnant. Je mesure le travail ayant construit moi même une monture à fourche. Je vais peut être vous prendre quelques idées :)
Very impressive work! Nice to watch. Hope you enjoy every minute with that mount!
It's not so easy, I still work on some improvements towards better guiding. But I will. Soon. ;)
@@astrovroobel 0.5" is not good enough?? You, sir, have high standards ;) But I do understand the tireless chase towards better guiding. Let the pictures judge!
@@astroboden The 0.5" is only what the mount can reach, but not permanent value.
@@astrovroobel Ok, well. Good luck with it. Keep us posted :)
Wow! Awesome job
Tym to mógłbyś zasilić jakieś poważniejsze obserwatorium ;) Świetna robota!
Dzięki :)

Brawo Astromaniaku :)

Awesome
Thank you :)
12:16 ... bro, fucking nice 👌👌
Bravissimo🙂🙃🙂da Venezia
Comme toujour super mon amis
Thank you.
really impressive but does it perform better than commerical tracking mounts?
Thanks. I think I have to still work on it to get tracking like the better commercial mounts. 0.7 arcsec guiding in the UK seeing is not bad for the ATM.
Next step is building mount for unguarded imaging.
hey welcome back with a new project :) my bresser 10" need goto haha :)🤣🤣 ça coute trop cher une eq8 😂 félicitation :)

Was that MKS board the 8 but one? Cool project.
Thanks. :)
It was MKS L-Gen v2.1.
nice
Excellent work! What are the gear ratios on both axis? How did you gear both axis? I know the RA has the harmony drive.
Hi,

How much did the whole mount cost? Amazing work btw!
More than I assumed. 😊 Thanks, btw. 😁
pls can give an estimate, i want to build one for my 8 inch dob

Wywaliłeś biały bojler? Co to za refraktor w zamian?
Nie, nadal jest, ale narazie w odstawce. Trzeba go wzmocnić, może przez wymianę tuby na carbon, albo co najmniej przez owinięcie okolicy focusera. A refraktor to Altair 102/715 EDT Triplet APO.
Excellent but was that music really necessary. 5 mins was all I could handle.
I mean, all you would've had to do is mute the video and play your own or watch in silence...not that difficult, yet you abandon the video, halfway through, instead?
Its not pointless its just very European. . . Why use one part when more will do!
Nice work but god, this music is horrible.
Volume down or mute.
