What was the diameter of the telescope that Charles Messier used to make the Messier Catalog?

Borg · Mar 22, 2016

Messier telescope was a 100 mm (four inch) refracting telescope.

Thanks for the answer.

Borg · Mar 22, 2016

You're welcome. It was pretty easy to google.

AstroCody · Mar 22, 2016

I would imagine. I tried finding it before but didn't search for the right thing.

Borg · Mar 22, 2016

It happens. I was called a google master by someone on the forum once but there are still times when I can't find the chair that I'm sitting on. :oldtongue:

SEDS has a page with information from a 1807 book listing the telescopes Messier used between 1765-69.
