F is effective focal ratio.
Thanks, I was thinking that, but wondering how you get f/36.6 on a C8 with a 2x Barlow. I'm not good at all these calculations .. :)

Sorry to make you confused. Actually I am using 2 barlow with 2x each. The way to connect these two barlow give the effective focal ratio at F36.6.
