You will need to install Libre Office Draw (free) to ensure printing of the segments at scale.

good job
I am impressed by your passion.😊
That's awesome.!
Thank you, glad you like the content :)
🎉super класс
I wonder how difficult this would be to adapt to my latitude of 65 degrees north, excellent project!
I do not know if it is enough to just calculate a 65 degree segment.. the platform has been tested only up to 56. I can calculate you a 65 segment and then feel free to give it a try.
@@astralfields1696 I have summer vacation coming up in couple weeks, and the tools and I think I also have one of these motors already so I would love to give it a try!
I have re-uploaded the plans to include a 65 latitude. Do let us know how it went and if it worked out well.
@@astralfields1696 Will do, thank you so much for the help, this time of the year is the building / tinkering time here cause sky does not get dark even at night till fall.
Great freaking video! Question, can I just build this platform of this size and use an 8 inch dob on it instead? That wouldn't cause any problems with tracking would it? And the platform will be there when I upgrade to a bigger telescope.
Yeah.. this platform will handle an 8" very easily with a single motor. You can add a second one later for a 12".
Hey this is awesome! The blueprints for the "segment" piece don't seem to include my latitude (41.72 or about 42 I suppose). Is it possible to provide either a print out, or how to calculate the shape of the circle (or ellipse?) so I could maybe make my own, thanks.
Hello , the problem is beyond the latitudes in the design , the whole platform needs to be re-designed with different dimensions, it is no longer only about the segments.
What I could suggest is going with the 46 segment and then raising the southern pivot by 3-4 degrees to catch up to Polaris. This should do the trick without risking a toppling your telescope over.
@@astralfields1696Hi, my latitude Is 45°. So I should also be able to raise the southern pivot by about 1° (using the 46° plans) to align with Polaris?
Yes , it should work very well even without raising it by 1 degree.
Great video, I just build a Arduino tracker with adjustable speed.
amazing video, this will help me a lot in the construction of the platform but I have a question: do you reccomend it for astrophotograhpy? I don't need the precision of a $ 1000+ eq mount but if this platform can track without problems any object in the sky for 30 seconds or more I will be more than pleased.
30 seconds is not doable unless maybe at magnification of 30x.. 5-10 seconds is ok if you spend time and care to perfectly allign fhe platform to polaris as well as the speed of the motor.
@@astralfields1696 Oh, alright no problem. I will use the platform primarily to help me maintain the general direction of the target when I'm doing visual.
@@Tommaso_Dal_Santo For visual no problem at having the target dead center at 400x magnification for over 5 minutes :)
In the previous video on the platform you mentioned WestMarsh's plans? I cannot find them anywhere. Thanks for this I'm going to do it!
Yeah it is a bit buried in the discussion. Here is the link to the comment with the plans:

@@astralfields1696 Thanks so much mate, and for your hard work in showing the public your plans. I'm gonna try this at 37 degrees lol (Melbourne Aussie). I know it's a bit steep or shallow. I have confidence to do this because Damo did something similar at 33 degrees, it must be Sydney. "The Equatorial platform is the answer to astrophotography.... etc'. Cheers and thanks again! ruclips.net/video/QWkX159fwXg/видео.htmlsi=JnmHB71k5ixoSSPW
Cool.. that is great if you manage to get this working so low.
Sam też niedawno zrobiłem platformę , z tym ,że na płozach z blachy aluminiowej 10 mm . Na wałki kupiłem wężyk gumowy i go naciągałem . Ja używam 1 napęd EQ i nic się nie ślizga poprzez zastosowanie tego wężyka gumowego. Polecam jeszcze zastąpić ten potencjometr od ustawiania obrotów , potencjometrem precyzyjnym wieloobrotowym .
Nah mate, no need. Mine works perfectly as well with this setup, worry free 😉
The one motor is doable but this way with two the load is better distributed and the motors don't have to struggle at all.
Hello,
Very well done.
I don't have access to the link which you have shared.
Please grant access or make these link public.
Thanks
Thanks for checking that, now it should be fixed
Yes, thanks.
Thank You for the Video. Planning to build one for myself. How do I calculate the curve for a 43° latitude?
Hello , once you go below 46 things get tricky. It is not just about the curve but also the entire length of the platform, it also needs to be made larger and longer so that the axis of rotation at Polaris fits better the center of gravity for the telescope. This is why the plans do not contain any curves below 46 and above 56... basically the whole thing needs to be redrawn and in some cases even the whole design changed to a different type of platform.
For 43 you could try building it with the 46 and then raising the south part of the entire platform by about 3 degrees to match Polaris.. or less .. whatever your physical situation allows without toppling over anything. Even if you leave it at 46 without raising the south part I believe the tracking will be acceptable.
Thank you for the quick reply. I believe I will build one with threaded feet so I can adjust the south foot to adjust for the change in latitude. Once again thank you for a great video.
Is this the same size you built for your 8" Dob or did you upsize it?
You will find the dimensions for the 8" in the plans attached to the video.. second half of the document. It is about 20% smaller.
I have a question.
Is the 46° segment ok even if my latitude is 45°? Otherwise how do I calculate it?
Thank you
Hello , yes that is perfectly fine. You won't even notice the difference. If you want you can also raise the whole platform once on the ground by an extra degree.. this will ensure perfect Polaris alignment with the 46 segment.
@@astralfields1696 thank you so much.
I forgot to add.. raise the entire platform at the southern tip by an extra degree :)
Would you be able to build me one, I have a 10 inch dob, is there a way to contact you?
My email is evel30m@yahoo.com .. I am in the Czech Republic.. Unless you are nearby the shipping will be too expensive.
@@astralfields1696 dang I live in usa I don’t think I’ll be able to make it. I saw that it is possible to buy motor kits for it but it just seems too complicated
Did you check the attached plans under the video? You need a simple Celestron EQ motor, some wheels etc snd you ate good to go. I have the parts list there too
@@astralfields1696 yeah sounds good, me and my dad will try it out, I am just confused on what you do to get the motors to track. I also don't understand what the segments means and how to adjust it to my lattitude.
It is a bit of a long story if you want to understand how it works
www.reinervogel.net/index_e.html?/Plattform/plattform_VNS_e.html
But you don't have to , just construct based on the plans and print & cut the segment that is for your latitude. The motor has an adjustable speed so once constructed it can be set to the right speed. The platform has to be facing with the segment sides to the north for it to work.
