Focal Ratio help
Hey there,
I am new to this forum and astronomy but have a quick question. I am stuck between these two scopes: bintels bt200 8inch one is 80 cm f/4 and 100 cm f/5. The f/4 is 5 bucks more expensive but I was hoping someone could tell me the advantages of each scope while considering if the larger scope is to big for the mount. Also, if I got the f/4 could I get eyepieces to get to the equivalent magnification?
Thank
(Sorry ignore repost)
