For Sherwin Cashie, the answer began with a deep interest in astronomy and astrophotography. Through AstroIsland, he has turned that specialist passion into educational content that can reach viewers far beyond the Caribbean.
In this October 9, 2026 edition of The Digital World, Keron Rose speaks with Cashie about building a channel as an adult Caribbean creator, finding a global audience, earning from expertise, setting up the payment systems needed to get paid and attracting brands in a highly specialized niche.
The Digital World — Full Interview
Watch: Sherwin Cashie on building and monetizing AstroIsland
A practical Caribbean creator story about finding a niche, reaching the world and turning useful content into opportunity.
A Caribbean channel with a global subject
Astrophotography is a demanding mix of science, patience, cameras, telescopes, software and careful image processing. It is also the kind of interest people might dismiss as too narrow for a Caribbean creator. AstroIsland demonstrates why that assumption is outdated.
Cashie creates tutorials, software reviews, equipment demonstrations and educational videos for people who want to photograph and process images of the night sky. The audience for that knowledge is not limited by the size of Trinidad and Tobago. A useful tutorial about an imaging workflow or a new piece of astronomy equipment can be discovered through YouTube search by viewers anywhere in the world, and it can keep helping people long after it is published.
That is one of the most useful lessons in the interview: creators do not have to copy the subjects that already dominate their local feeds. Specialized knowledge can be an advantage when it solves a real problem for an identifiable community.
Starting as an adult changes the story—not the opportunity
Cashie’s journey also challenges the idea that serious content creation belongs only to younger people. AstroIsland is built around experience, curiosity and the willingness to keep learning. Those qualities matter more than fitting a familiar influencer stereotype.
The conversation looks at the unglamorous work behind a growing channel: becoming comfortable on camera, learning to record and edit, improving titles and thumbnails, building consistency and moving from the first subscribers towards meaningful milestones. It also asks what changes when a creator realizes that people outside the region are actively looking for the knowledge he can share.
The larger point: age, geography and an unconventional interest do not disqualify anyone from the creator economy. The real work is learning how to package useful knowledge, serve an audience and build systems around the opportunity.
Monetization is bigger than advertising
For Caribbean creators, discussions about YouTube income often stop at one question: is the platform’s advertising programme available in my country? The interview pushes past that narrow view.
A channel can create several routes to revenue: audience support, memberships, merchandise, affiliate relationships, product demonstrations, sponsored collaborations and direct brand partnerships. The value is not simply the video view. It is the trust and authority a creator builds around a clear subject.
Cashie has openly followed Keron Rose’s guidance on YouTube monetization and payment stacks, then applied those lessons to his own creator journey. That makes this discussion especially practical. It connects content strategy with the less visible infrastructure Caribbean creators need: accounts, platforms and payment methods that can actually receive international income.

When expertise begins attracting brands
The commercial signals around AstroIsland are becoming clearer. In the interview, Cashie discusses brand opportunities that have begun to reach him, including a relationship with Leviathan Optical, the company behind the Spectral Pro light-pollution filter, and DWARFLAB, which sent him its new DWARF mini Smart Telescope to test and feature. Cashie held the boxed telescope up on camera during the conversation—tangible evidence that AstroIsland’s specialist audience is attracting companies that want credible creators to introduce new astronomy products to the right people.

That matters because it shows what can happen when a creator earns credibility in a defined niche. Brands do not need a creator to appeal to everyone. They need the right creator to reach the right audience with knowledge, context and trust.
