Hello! I am learning about refracting telescopes and am slightly confused. I have read that a refracting telescope will magnify planets, but not change their brightness, but will not magnify stars as these will remain as point objects. It just makes the stars appear brighter. I am slightly confused by this because reading through my text book, it seemed like the refracting telescope produces a magnified image of a star and the image is inverted and virtual,,, although I can't understand how you produce an enlarged image of a point object either! I am also confused because I understand that the stars will appear brighter because the objective lens collects more light from the star than the pupil, but then why do planets not appear brighter by the same principle? Thank you in advance!
