John and Asbytec
I'm glad you are enjoing the book,this is the kind of stuff I like.
The trophee of today is the booklet ''Hints on Reflecting and Refracting Telescopes'' By Horne Thornthwaite,London,1880 ,downloaded from archive.org.

I agree with you.There were apparently quiet nights when not even 236x was able to split 52 Ori.It was the first time to split 52 Ori at 144x.

One thing I intend to do is to dig and find where Kitchener ,Admiral Smith and John Herschel made that statements.
It will be not easy,I had read the book on telescopes of ''old quaint'' Kitchener and don't remember the quote about Rigel.But there are so many informations packed in that small lovely book and being age 58 I noticed my memory is no more what used to be (or at least my wife say so)!

Clear sky to all of you,now I'm going under the stars to try my luck with Eta Ori and 32 Ori.

My sketches of this pair from a couple of years ago.
Scope used was 150mm f/8 refractor and aperture mask.

Sadly, lots of measures and no calculated orbit from the wds.

Did you ever use aperture masks to determine the aperture limit for splitting doubles?
