It can be challenging to determine who specifically bought an item from Craigslist, as the sales are typically conducted privately between the buyer and seller, with no public record of the transaction. If the buyer or seller chooses to share this information on forums or social media, that would likely be the only way to know who purchased the telescope. Enthusiast communities dedicated to astronomy or specific telescope brands may discuss such transactions if they are of interest to the members, but these details would not commonly be available in a public database or record.
