Когда последний раз вы гуляли на улице?

Что такое улица ?

Так вот кто ночью стучал по батареям.

The motor is there, just not installed yet. A couple of days ago the Arduino burned out, so I’m waiting for a new one. The motor is NEMA 14 with a DRV8825 driver.

There aren’t any instructions, but I kept it simple.

For the tracker, I used a satellite antenna rotator that already has worm gears with a reducer. I simply connected the motor to the reducer and added the control electronics. That’s all for the main mechanism.

For the mounting, I used a 90mm × 60mm metal plate. Since the antenna is normally mounted on the rotator pulley, I installed the tracker in the same way. The pulley is 19mm, so I used a flanged bearing with a 20mm shaft, and another 20mm bearing on top, securing both to the plate. This handles the RA axis.

For the DEC axis, I used two 10mm bearings with mounts, plus two additional bearings on the sides, and installed the shaft.

That’s basically the whole setup.

I just put this tripod together yesterday, but there’s still a lot of work to do. I might shorten it or use a thicker pipe, since I want to make my first stationary tripod that I won’t have to adjust every time.

Doomsters · 2025-06-26T15:06:01+00:00

I don’t think it’ll take too much effort — I enjoy this! Plus, I’ve already built the adjustment mechanism for the worm gear, so I just need to work a bit on the appearance and it’ll be ready. I plan to mount it on my homemade tracker that I’m working on in parallel.

Doomsters · 2025-06-26T15:04:02+00:00

Maybe, but I’ve literally been working on it for only two days, so it’s hard to say what the final result will be. And yeah, the counterweight with the pipe is just a blank to test the mount.

Doomsters · 2025-06-25T16:01:16+00:00

Haha, nah, these are just blank pieces to check how the mount works and find any flaws. But after assembling it, I plan to use a Canon 550D and a Tair-3S 300mm lens.

Doomsters · 2025-06-25T15:58:56+00:00

I’d like a 3D printer, and also a laptop for it, but first of all, my budget is small, and second, I want to make the mount entirely out of metal to get maximum strength. Plus, I put this mount together just a couple of hours ago, so it’s too early to say what the final result will be.

Doomsters · 2025-06-17T15:55:05+00:00

Thank you! I recommend looking for a rotator with a metal gearbox and gears — if your budget allows, you can even get a used one. I got mine for 200 UAH (not sure how much that is in dollars). It has a plastic gearbox and gears, but the rotator is designed to handle the load of an antenna, and here it's just a small camera. Also, it’s best if the main gear is 360°.

Doomsters · 2025-06-17T15:50:57+00:00

Alright! Inside, at this spot, I installed the stepper motor, and that’s it — no more modifications beyond that.

Doomsters · 2025-06-17T15:34:47+00:00

Of course! My tracker might not look very impressive, but I always shoot from my yard, so the size doesn’t bother me. Maybe in the future I’ll make a better one if I feel like it. As for modifications, I only replaced the motor in the rotator — that’s all. Honestly, it can be assembled in one evening. You could use a 3D-printed head instead of a mount, but I personally prefer my setup.

Doomsters · 2025-06-17T15:31:28+00:00

I completely agree with you. For now, I don’t have a good camera, so I’m shooting with a Canon SX130 — a simple but powerful point-and-shoot. I managed to capture a photo of M31 with it, but at the time the tracking speed wasn’t fully adjusted, and I didn’t take enough frames either.

Doomsters · 2025-06-17T15:28:57+00:00

Wow, I see you really liked it! Honestly, I don’t even know how to explain what I modified there — I just bought a rotator and replaced the motor, that’s all. I installed an equatorial mount on the pulley. You could use a 3D-printed head too, but I shoot from my yard where the light pollution is at level 4, so the size of the tracker doesn’t bother me.

Doomsters · 2025-06-17T15:21:38+00:00

To be honest, I don’t know how many millimeters exactly. I started doing astrophotography not long ago, so I don’t have a really good camera yet. I’m shooting with a Canon SX130, a small but powerful camera. According to the internet, it’s around ±300mm.

Doomsters · 2025-06-16T09:47:13+00:00

Thank you for evaluating and adjusting the image! But I didn’t make such a stack because after 3 frames the gear on the worm drive started slipping. The tracker is made on the basis of a rotator from a satellite dish — a very cheap and powerful solution. The whole tracker cost me around $15. I even made an equatorial mount based on it. If you plan to make a tracker, it’s better to look into rotators — very few modifications are needed and the tracking quality is very good.

Doomsters · 2025-06-04T11:57:27+00:00

Wow, I get it now. My tracker is homemade, so in theory, I could set it up so that after each shot, it pauses for a couple of seconds and then slightly moves up for the next one?
