Chris Posted December 4, 2022 Share Posted December 4, 2022 (edited) I do try and limit the number of videos a share on SGL as I don't wont to spam the site with the things! However, I thought this one might be worth sharing as a bit of a star testing primer. If anyone spots any errors please let me know, I can always add a pinned comment with amendments etc, otherwise I'm wondering how many of us star test our scopes considering it can tell us so much?
