I saw on YT how they farm legendary asteroids. So i build my own ship. It now has 248 time traveled (see the count on the sidebar) between nauvis and vulcanus. It "only" got 36x8 legendary aseroids. (Counted the belts). So: Let they run it over night? What do they do to get a lot of legendary?

• More asteroids! Try a different route which has more / larger Asteroids in it, farther out in the Solar System.
• More Speed! The faster you travel,the more asteroids you will encounter per Time.
• Solar Panels are only useful / mass-efficient for Nauvis-Vulcanus; your platform space (and therefore Weight, which decreases the Speed) is better used on machinery. It looks like you already have Nuclear Power started.
• Laser turrets are the worst choice for Asteroids, which have a large Resistance to that damage type. And they use a lot of power. Bullets, Rockets, and Railguns work great; ammo for all can be manufactured in space. Don't forget the Damage Upgrade researches.
• Higher Quality Collectors have more Arms, which will collect more Chunks (versus letting them splat uselessly against your Platform's bow).
• More Collectors! Most turrets can be spaced behind them; not between them. Quality Turrets have a higher range to compensate.
• Tangential: Chunks do not Stack; so Bulk/Stack inserters are a waste. Fast Inserters (blue) have the same Rotation speed.

Good Luck!

When bootstrapping, use less crushers with better quality modules and dynamically change the recipe. For example, if you only have 2 legendary quality 3s, you should use them in one crusher and make it handle all the epic recipes, or even the rare ones.

The Lasers are intentional that I don't use asteroids for ammo. I remember, as I started that ship I let it run many times but I haven't had legendary science unlocked.

Build a second farmer ship. Let's see how it develops

I am unsure, how to process the legendary asteroids. One things seems clear: Crack them in space into ores,calcite,ice, carbon and sulfur. I guess its best to send this to a planet.
Would like to use foundries, but fluids lack quality. The ice, just process it into water. The rest: Obviously plates, coal and then legendary circuits and plastic. But plastic needs petroleum which lacks quality ...

As it is low volume: Maybe a sushi belt? I would like to avoid bots here as they could mess it up....

Any hints would be welcome

• Carbonic Asteroids make Carbon & Sulfur - useful for Coal Synthesis, Explosives, and Plastic.
• Metallic Asteroids can be smelted directly Iron/Copper in a Furnace; no point in using the Foundry recipes with high-grade Inputs since Liquids "reset" to Normal quality. You can get Unlimited Liquid Iron/Copper on Vulcanus and use Recyelers to upgrade the Plates to Legendary.
• Oxide Asteroids are not as useful - I usually reprocess these to Metallic/Carbonic. Ice is a key component of Space & Cryogenic Science. Calcite can be used in Artillery shells, but those turrets do not auto-target Asteroids.

A lot of the challenge is ensuring you are producing the right quantities of each Intermediate - recipe swapping (or priority-fed Splitters) are your friends.
