Hello, in another video (maybe the 1st version of the equatorial platform, not sure) I saw that the speed of the motor is preprogrammed. That means that the speed of the motor is related to the arc of the bearing I assume. Would you please explain how you would determine that?
@horvathtamas3476
@horvathtamas3476 Жыл бұрын
Hello, the known data is the diameter of the drive cone, which comes from the design. The revolution of the drive cone is 1 rev /24h. The drive cone is driven by a drive wheel, which has a smaller diameter, creating a gear ratio. In most cases, an additional transmission is needed at the motor as well. Therefore, the speed of the motor can be calculated based on the speed of the drive cone and the gears.

Does the version of the platform depend on how far north or south that I live or where I will be using my scope? I'm in North America, United States and I live in a town called Idaho Falls in the state of Idaho. I also travel to Southern Utah and use my scope there as well. There's several hundred mile difference.
@horvathtamas3476
@horvathtamas3476 Жыл бұрын
It is depend on where you would like to use it. Idaho Falls coordinate is around 43 northern latitude, so you should buy the model 4045. From this year it will be possible to order the segments separately, so you can easily change it, and the controller can be adjusted to the other model. It means if you buy a model 4045, you can order annadditional segment set, for example 3035 or something.

Interesting design! I built similar but made a U shaped part that holds the rings and bearings (brass/Teflon in my case) which allows the rings to be opened for removal of the OTA or rotating the OTA easily. I used a lazy Susan bearing to replace the record which turns better than my record allowed. I inserted a tiny 1/4" thrust bearing at the top of the center pivot which also helped the smooth operation. Fun stuff to play with.

Really tidy design! I love how you used two layers to create a template for your parts as an assembly aid. There was some hand drilling where I couldn't see how the drilling locations were marked - not sure what you did there. I'm an apartment dweller without a workshop and hope to design something like this, using commercial or makespace CNC or 3D printing of an easy-assembly design. The shapes look really sleek, with excess weight cut away - they make plywood sexy. (Though I appreciate all the astronomers who do have manual woodworking skills and home workshops too, who also make very functional platforms!)

Hi, very original idea! May I ask you how do you align the rotational motion with the polar? Is there a correct inclination of the shaft? What is the fixed point where the rod must be anchored? Should it be set to 180 ° azimuth? Thanks.
@horvathtamas3476

This is an old technic, not my idea. The altitude pivot point of the Dob, and the pivot point of the additional mechanism point to the Polaris. The disadvantage is, that this mechanism can be used only at the Southern sky. I mean from E to W.

Like many, I am extremely fascinated by what you have constructed here! This is such a simple and elegant approach to basic tracking for a Dob. I understand that an EQ platform is better, but I still want to learn more about this method and replicate it for my telescope. I would just be using it for Southern sky observation from 40 degrees lat. I have researched old methods and can't seem to find anything on this. So, Horvath, is there a name for this method? Who invented it? Your lower pivot point is raised from the base. Is there a calculation for that? Any math or specs you can share with us will be greatly appreciated! Thanks so much for revealing this technique! Well done!
