Hello! Welcome to Wikipedia, and thank you for your contributions. At least one of your edits on the page Newtonian telescope, while it may have been in good faith, was difficult to distinguish from vandalism. To help other editors understand the reason for the changes, you can use an edit summary for your contributions. You can also take a look at the welcome page to learn more about contributing to this encyclopedia. Thank you. Perey (talk) 09:55, 2 December 2021 (UTC)
