Another reason fluorite is better than glass

[MortonH]

Recently I've been Googling refractors a bit, especially those with ED glass. I must have included "ED" in my search terms once too often as my Spam folder is now full of emails offering to cure my 'ED' problem!

Non-use of fluorite leads to equipment dysfunction.

EDs? They're Erecting Diagonals aren't they? A simple way to get around the problem of feeling that your telescope is pointing in the wrong direction.

Since switching to an 80x400 refractor with an image erecting diagonal I feel like my world has turned the right way up again. (Genuine unsolicited Customer endorsement)

If you had searched for fluorite you'd be getting teeth whitening spam now

But of course, the real problem here is Google...

Google's an eager beaver, for sure...

When I turned 70 I decided I needed a couple of fresh hobbies to brighten up the declining years and chose Astronomy and Whisky, both of which promised the possibility of a great deal of interesting research.

For a couple of weeks I regularly Googled the local Dan Murphy's which carries a good range of whisky, as a starting point for online research about the various brands and styles. It wasn't long before I only had to type in the first two letters - "Da" before Google would suggest "Dan Murphy" ?

I was half expecting it to start popping up with "Alcoholics Anonymous now?"
