Fantastic job

Absolutely fantastic piece of work, Jon - you are mastering your dromne beautifully!

beautiful

How’s life?!like!you made nice dji, 🤘

Very interesting information, thank you for sharing. I dont believe i have heard someone talk about this equation before, so that means time for some digging and reading about it!

Ok, pixel size between 1-2 arc sec is best. But it's another problem - periodic error. If you have SW Star Adventurer it has go periodic error around 1,5 arc sec, and even with guiding error will be around 1 arc sec. So probably the best is to have 1,5-2 arc pixel scale to avoid problems with trackers (especially over 180s exposures) or get harmonic mount (like AM3/AM5) and guiding. Also at very wide field AP like on 135mm it will be extremaly hard to gave under 2 arc sec pixel scale (you would need aroud 1' pixel size sensor). In Siril you can drizzle undersampled images to get better results

Hii pls reply I have a telescope Celestron 114 eq can I use my telescope tripod to put star tracker on it

Why 206?

Thanks, great info. I have a Canon 6Da and a Canon R5, and plan to use my Canon EF 100-400mm L lens to shoot nebulae. Using the equation, my 6Da is over the threshold of 2, but as long as I use the R5's crop mode, and zoom to at least 450mm, this camera-lens combo falls within the rule of thumb. So that is what I will mainly use. It would have been nice to use the modified camera, but I'm sure I'll get good results with the R5.

Great minds think alike... I have just started in astrophotography and didn't want to spend ££s on an expensive tripod which could only take 15-20 lbs. I have ordered the Bosch BT 160 from Amazon. I am going to modify it your way for the base but not the legs as going to use a sandbag holder to hold powerbank and extra bits. Got a small compass to stick to the base to align North and some RV bubble levelers to easily level the legs.

might add that the oversampling threshold is affected primarily by astronomical seeing. the thicker and less stable your atmosphere is, the more bloated your stars will be, meaning that oversampling threshold (1"/px in this video) will need to be higher. This is why space telescopes with a large focal length can still get pinpoint stars. Personally i dont think too much about over/undersampling, especially under. It's quite easy to process with starnet or the new starX plugin, but good to keep in mind. great tutorial!

I bought this same tripod a few months ago, just have to change the mounting bolt to a 3/8s I also installed and table underneath to hold the legs together and at the right dimension. I also put RV levels on three side of the head. Works great 👍

tighten a lashing strap around the legs

Very nice. What product are those black-headed bolts that you screw into the riveted holes with the black stops on top of them? What are those? And what kind of wing nut was that exactly in the middle?

Which is better for astrophotography? The star adveturer 1 or the iOptron Smartstar Cube Pro AZ? 🤔

Great idea 👍

I am looking for one of these. Had the idea when I got one last month, Home depot used to carry them in the store, now they are out of stock. Maybe alot of photographers are using them? lol But thanks for the video. You answered some questions I had about them.

Great ideas! I was considering this route as the tripod I ordered became backordered

I was gonna do the same thing with that same tripod and I came to the conclusion it would be too many alterations. I ended up with the K&F Concept carbon fiber tripod for $180 and it is great. A great tip for adding extra stability to a tripod is hang your bag underneath or use a bungee cord and tent stakes driven into the ground.

Great video. I started using a survey tripod for astrophotography last week and as long as I push it firmly into the ground, it tends to remain fairly stable. I also used the same washer approach for attaching the azimuth base. Rock solid.

I have a 3d printer so im going to go get one of these and print a leg stop system and a adapter that fits in that hole. I'll also adapt the leg lock system so it can hold some weight.

Thanks for the hack, much appreciated :) Agree about the tripods being really expensive at least at this stage of my journey! A question about the legs movement range extending too far. Why is it a problem? Is it that they can accidently move and need to be stopped (too loose)? Trying to decide if the leveling tripod would still work with only the center bolt change and not the leg stoppers.

Indeed a very practical hack! This camera tripod issue is very common and nobody discusses it when they talk about trackers. Thanks for addressing it.

nice work!

You used the same rivet machine to install the screw inserts from the first video?, thanks for posting this idea

Simple but effective...Great hack buddy, thanks for sharing. :)

A spot on idea

Sweet vid! Nice use of the rivets
