The largest astronomical refractor has an aperture of about 1 meter. What is the main reason why it would be impractical to build a larger refractor with twice this aperture. O Glass can only be cast in meter size diameters O Secondary reflections ruin the image for larger diameters O The glass is strong enough, but the steel tube sags O Glass sags under it own weight
