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?"
