What happens if I don't like the result?

Every credit comes with our Result Guarantee. If you're not satisfied, we refund your credit instantly — no questions asked.

Do I need experience with image processing software?

Not at all. Cosmos Darkroom was built for everyone — from complete beginners to seasoned imagers. The automated pipeline handles the complex processing.

Does it work with my telescope?

Yes — Cosmos Darkroom works with any telescope: smart telescopes (Seestar, Dwarf, Vespera, Unistellar, Celestron), Newton reflectors, refractors, and any optical setup.

How long does processing take?

Most images are ready in 30 seconds to 2 minutes, depending on file size. Pro subscribers get priority processing.

Do I need a powerful computer?

No. Everything runs on our GPU-accelerated cloud. All you need is a web browser — works on any device.
