Considering that the general public wouldn't have have a clue what we are talking about anyway I suppose it doesn't matter how we pronounce Astro names and terms.
I've heard some funny ones when we get together at Camp
Alder-Bran, Al-Dabberin, Alder-Barren, Orl-de-bran, and that's just for 1 star!
then there is An-tar-eez, Ant-air-eez, ant-ar-ess, Ant-air-ess etc
No matter who writes a list, that list will be in that countries accent.
I'd love to see an Australian Pronunciation list
