I fiured it out, if you divide the focal length by the aperture you should get the focal ratio, (according to what I have read). This should give the Celestron g8n a focal ratio of f/10.

: I am also new and have been searching for several weeks for a 1st scope. I have found a plethora of useful information out there including this site.

: Try these links.

: The top 2 have specific focal lenght descriptions. The bottom one just alot of good information.

: : :

: : BTW the only G-8n I see at Celestrons website is a 1000mm (f/5)

: : ,Blink
