Interesting question Peter.
While I agree with Colin that it looks similar to a result of drizzle integration, the main difference is that higher resolution data acquired with a Barlow is not a result of mathematical manipulations as it is the case with drizzle integration.
But if both methods produce similar results, then why bother with large telescopes? Unfortunately I don't have an answer to your question Peter, but sometimes I ponder whether the reason for us seeing more detail in some splendid amateur space images is not because of them being taken with larger telescopes, but more so because of premium mounts being used, better cameras and filters, and perhaps even more importantly, inspiring results are due to superior data processing skills of those few truly gifted and experienced amateur astrophotographers.
